Bug 59258 – perl-5.8.4-r1 build fails on alpha

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Andrej Filipcic 2004-08-03 06:16:27 UTC]

Building of perl-5.8.4-r1 segfaults when miniperl is called on alpha when using
gcc-3.3.4-r1 and glibc-2.3.3_pre20040207. It appears that the size of sitearch and sitelib in perl.c is too small in some cases...

Here is a patch:

This may not just be alpha-specific. Can you describe what conditions made
these variables overflow on your machine?

Please, remove the bug. I discovered that I have made a backup (/usr/lib/perl5/5.8.3.tmp). That is why the ebuild crashed.
