[SOLVED] -current64 aclocal segfault

KaMii · 11-06-2015, 08:20 PM

just type aclocal --version and you get this nice little segfault in dmesg

[ 9667.668753] aclocal[6105]: segfault at 5 ip 00007fb985585f03 sp 00007ffed8f35dc0 error 4 in threads.so[7fb98557f000+9000]

Versions installed:
automake-1.15-noarch-1
perl-5.22.0-x86_64-1

Not sure if this is an issue just for me or if its for everyone. If its only on my system, I have no idea what I can to do fix it.

FWIW I get no segfault with `aclocal --version`.

Didn't happen on my system... Running the latest version of Slackware64-current with the 6 NOV update (mozilla-nss).

Works here as well. I'm using the stock 4.1.12 generic kernel.

Ok we get that its working on other systems, we don't need anymore of these posts. What caused it to break on mine? Ideas?

bassmadrigal · 11-07-2015, 12:09 AM

You already suggested the kernel... have you tried reverting back to the stock kernel?

KaMii · 11-07-2015, 12:45 AM

Got it working! so solved and here is the issue:

Purge all perl modules first before upgrading perl, I had an old module hanging around that was causing segfaults. I have no idea which one it was, it was one that was installed by cpan. And since CPAN was also segfaulting I had to fix the issue by first removepkg perl then physically deleting every perl directory that was still hanging around, then finally reinstalling perl.

hi KaMii, looking at this

Code:

/usr/local/lib64/perl5/auto/threads/threads.so

I suppose you have another perl installed in /usr/local: what does

Code:

which perl
perl -v

say?

EDIT: ops, just read above.
