From ilya@math.ohio-state.edu

This is a bug report for perl from vera@​ia-ia.uucp\, generated with the help of perlbug 1.33 running under perl v5.7.2.

The following module​: ======================== xxx.pm use strict; sub AUTOLOAD { $constname || $!{EINVAL} } 1;

emits

  Unknown error   Compilation failed in require at -e line 1.   BEGIN failed--compilation aborted at -e line 1.

if you use it (e.g.\, perl -Mxxx). Apparently\, $! is set when $constname is set\, but the S_require_errno overwrites it with "". see the line before a call to yyparse() in pp_ctl.c​:S_doeval().

Enjoy\, Ilya

Confirmed @​14663\, but 5.6.1 and back seem ok.

With this small patch\, the output now is

$ bleadperl -Mxxx -e1 Global symbol "$c" requires explicit package name at /home/rafael/perllib/xxx.pm line 2. BEGIN not safe after errors--compilation aborted at /home/rafael/perllib/xxx.pm line 2. Compilation failed in require. BEGIN failed--compilation aborted.

Better ideas ?
