This is a bug report for perl from thepler@​genome.wustl.edu,
generated with the help of perlbug 1.39 running under perl 5.18.0.

# is this difference in $? expected or a bug?

$ perl -e 'use warnings; local $?; qx(command_not_in_path_arglebargle 2>&1); print "$?\n";'
-1
$ perl -e 'use warnings FATAL => "all"; local $?; qx(command_not_in_path_arglebargle 2>&1); print "$?\n";'
0
$ perl -e 'use warnings; qx(command_not_in_path_arglebargle 2>&1); print "$?\n";'
-1
$ perl -e 'use warnings FATAL => "all"; qx(command_not_in_path_arglebargle 2>&1); print "$?\n";'
512

I tripped on the zero case (the second invocation) above. I expected $? to be non-zero after the qx().

I get consistent results for the above on 5.8.7, 5.10.1, and 5.18.0. Those are the only versions I tried.

I tripped on the zero case (the second invocation) above. I expected
$? to be non-zero after the qx().

Those are the only versions I tried.

I got similar results for perl 5.18.0 on Darwin/PPC and on Linux/i386.

The RT System itself - Status changed from 'new' to 'open'
