Hello,

I updated Rakudo from git last night and did a make spectest. Only one test failed, S02-types/bool.t.

It seems like if I run the entire test, it fails as shown in the attachment. But, if I comment out *any* one of the last dozen or so lines it runs to completion. Also, if I take the line at which the dump occurs...

*is Bool.roll(*).[^10].elems, 10, 'Bool.roll(*) contains at least 10 elems';*

... and place a copy of it after every existing line, the entire file runs.

I would think that this indicates that there must be some sort of boundary condition involved in triggering the dump, perhaps something like garbage collection.

Please let me know of anything you can think of that I could gather that would be helpful in tracking this down.

The environment here is:

Update:

I found that the bug also can be triggered with just this loop, usually after about 6-13 iterations:

(0 but Bool::True) and print qq{$_ } for 1..100;

Backtraces are attached for three recent versions of Rakudo, the current version from git as of about 2013-03-01 0700 UTC (2013.02.1-14-g357e603), Rakudo Star 2013-02, and Rakudo Star 2013-01.

It looks like this also failed with a sigabrt in the #perl6 evalbot, see http://irclog.perlgeek.de/perl6/2013-03-01#i_6511442.

Best regards, Ira

One more observation that might be helpful:

Whether memory allocation errors occur or not appears to depend on the data type on the left hand of the "but" operator. If it is either an integer or undefined or both, Rakudo will crash after a dozen or so iterations.

All the other defined data types I have tried on the left hand side work (or at least they don't crash; some of them aren't especially useful).

I *think* that this *may* indicate that the size of the left hand operand of "but" affects whether the crash occurs. (If it's an integer, the size of the integer does *not* affect whether the crash occurs, but judging from the output of valgrind, it looks like the NQP bigint implementation uses the bn_mp_... functions in libtommath, and the "digits" that represent the numbers are allocated and deallocated separately from the mp_int structure.)

If I ever have enough tuits, I will try looking at the valgrind output again, but there are a LOT of complaints about reading unallocated memory and using memory after it has been freed, even in the cases where there is no crash.

FWIW, here are the tests I ran... each expression is run in a loop 100 times.

These work; at least, without double free or other memory allocation crash:

"0" but True "0" but False "0" but "some_string" [0] but True [0] but False [0] but "some_string" {0=>0} but True {0=>0} but False {0=>0} but "some_string" 0.0 but True 0.0 but False 0.0 but "some_string" 0e0 but True 0e0 but False 0e0 but "some_string" 0+0i but True 0+0i but False 0+0i but "some_string"

These fail with double free or other memory allocation problems:

0 but True 0 but False 0 but "some_string" Int but True Int but False Int but "some_string" Str but True Str but False Str but "some_string" List but True List but False List but "some_string" Hash but True Hash but False Hash but "some_string" Num but True Num but False Num but "some_string" Complex but True Complex but False Complex but "some_string"

[The following number is 2^4095, written out, so the value cannot be less than 512 bytes long...]

These fails peculiarly ("Cannot look up attributes in a type object") but without a memory allocation error:

Rat but True Rat but False Rat but "some_string"

p6rt commented 11 years ago

From @FROGGS

Hi, labster and me already discussed that issues the last days (since friday or so via irc).

It is true that this branch merge made this bug visible, but we dont believe that the patch is to be blamed.

My rakudo-build on feather shows, that if you comment out one of the 51 tests of bool.t the test doesnt end in a backtrace...

I can attach diffs to show what we have tried.

p6rt commented 10 years ago

From @usev6

Since the tests in S02-types/bool.t pass, the relevant problem seems to be the for loop with "0 but Bool::True".

I don't see any crashes within the first 100 iterations, but on Parrot I get segfaults or crashes with around 262 iterations. On Moar and JVM there are no problems:

$ perl6-m -e '(0 but Bool::True) and print qq{$_ } for 1..1000;' 1 2 [...] 1000

$ perl6-j -e '(0 but Bool::True) and print qq{$_ } for 1..1000;' 1 2 [...] 1000

$ perl6-p -e '(0 but Bool::True) and print qq{$_ } for 1..1000;' 1 2 [...] 261 262 Segmentation fault

p6rt commented 9 years ago

From @usev6

As noted above the tests in S02-types/bool.t are passing for quite a while.

The only remaining problem was the segmentation fault with parrot when running '(0 but Bool::True) and print qq{$_ } for 1..1000;'.

I just tested with the latest Rakudo Star (2015.02) and I was unable to reproduce the segfault there -- even with more iterations:

$ perl6-p -e '(0 but Bool::True) and print qq{$_ } for 1..10000;' 1 2 [...] 10000

I'm closing this ticket as 'resolved'.
