Ardino IDE 1.5.7 cpp segmentation fault

[ziotibia81]

-Add "compiler.cpp.extra_flags=-fpermissive" to platform.local.txr -Install this DCF77 library: http://blog.blinkenlight.net/experiments/dcf77/dcf77-library/ -Compile the example "Simple Clock"

gpp has a segmentation fault. Tested in windows e linux.

Hmm, this is really a bug for upstream gcc then. Could you paste here the last few lines of Arduino's verbose compilation output (in particular the full gcc command that segfaults)? If you know how, the full preprocessed source would be good. If you don't, I'll show you the command to use after you paste the segfaulting command.

I have cpp preprocessed sources but I can't attach here. The error is:

Arduino:1.5.7 (Windows XP), Scheda:"Arduino Mega or Mega 2560, ATmega2560 (Mega 2560)"

Perhaps you could put up the preprocessed source on pastebin?

[matthijskooijman]

Ah, just noticed you sent them by mail, that's fine as well.

[matthijskooijman]

Ok, using that I can reproduce it here. I'll forward this to the gcc maintainers, thanks.

Further investigation shows that this problem isn't avr-gcc specific, it also occurs with regular gcc. Furthermore, I've reduced the commandline to just this:

g++-4.8 -Os -fpermissive ~/tmp/dcf77.ii -o /tmp/foo.o

which also crashes. However, using g++-4.9 does not crash, so it seems this bug was already fixed upstream (so I'll refrain from reporting it and investigate further). When Atmel and then Arduino update the gcc toolchain to a newer version, this bug should be automatically be fixed.

For reference, here's the offending preprocessed source. I've tried to minimize it, without any success (didn't try for long, though). https://gist.github.com/matthijskooijman/6f336497b4ad5741ff08

@matthijskooijman what about this issue?

@matthijskooijman up

This is a gcc bug, I guess we should close this issue and wait for a fix on upstream gcc.
