In light of the recently discovered fact that perl 5.8.1 breaks PAR, I haveuploaded a stopgap 0.75_99 prerelease on CPAN. It is also available here:
http://aut.dyndns.org/dist/PAR-0.75_99.tar.gz
MD5 (PAR-0.75_99.tar.gz) = e367146a023ab036379f48f47ad6ac4b
I'd like to invite all current PAR users with a C compiler to test this
prerelease, especially on dynamically-built Perl 5.8.1, to see if the
breakage still happens.
According to investigations by Abhijit Menon-Sen, Perl 5.8.1 has changed
fakeargv handling significantly, so line 62 of myldr/internal.c breaks
perl in subtle ways:
SvSETMAGIC(GvSV(tmpgv));
That can cause unpredictable segmentation faults.
In 0.75_99, I have simply tested for Perl 5.8.1 with #ifdef, and
disabled that line explicitly. This has the unfortunate side effect
that on dynamically-linked perl systems, "ps" and other tools will
display "par" (or "par.exe") instead of the actual pp-packed executable
name.
Users with 5.8.0 and 5.6.x should notice no ill effects.
If the test reports are satisfactory, I will release it as 0.76 and make
prebuilt binary releases. I fully intend to work with Nicholas Clark
and Abhijit to resolve this issue properly for Perl 5.8.2, and provide a
better workaround for 5.8.1 if possible.
Thanks,
