Well, for starters, I would try rebuilding without the crazy CFLAGS.  Try just
CFLAGS="-pipe" and see if it helps.  You might also want to try recompiling
sharutils/glibc with these new CFLAGS.

I will try that ( I am rebuilding glibc as I type this ), yet I think the
CFLAGS
are rather sane, but an experiment won't hurt.

not a bug in quake2-icculus

looks like your coreutils and/or toolchain is broken

should probably drop down your CFLAGS and re-emerge them

Please do 
ebuild /usr/portage/app-arch/sharutils/sharutils-4.4.ebuild unpack
and open /var/tmp/portage/sharutils-4.4/work/sharutils-4.4/src/unshar.c with
your favourite editor. Notice at line 438:

              name_buffer = (name_buffer == NULL)
                ? malloc (buflen)
                : realloc (name_buffer, buflen);

This is the bombing realloc. Please correct me if I am wrong, but name_buffer is
used uninitialized - it is defined just as char* name_buffer; ( line 361 ), so
it has a random non-NULL value and the trenarry-if tries to realloc it and fails.

Also, the rebuild of glibc and sharutils just completed - and did not help.

Reopening, and changed the title to better reflect the problem. This is not a
games bug, you may need to reasign it.

Also, downgrading sharutils from 4.4 to 4.2.1-r11 fixes the quake2 emerge
problem.

fixed in 4.4-r1 - thank you I've I'm going to email the current upstream 
maintainer.
