Bug 27492 – segfault in bfd_elf32_bfd_link_add_symbols in binutils 2.14.*

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Adam Chodorowski 2003-08-28 12:25:47 UTC]

There is a bug in binutils 2.14.* which causes a segfault in certain
circumstances when linking. This bug does not exist in binutils 2.11.*. It has
already been reported to bugs-binutils, and there is a fix in binutils CVS.

More details on the bug can be found here:
+ http://sources.redhat.com/ml/bug-binutils/2003-q3/msg00559.html
+ http://sources.redhat.com/ml/bug-binutils/2003-q3/msg00735.html

It would be nice if binutils 2.14.* could be patched locally in the ebuild
before an upstream version with this bugfix appears. Patch follows:
