All my printers stopped working suddenly.

Confirming, and I think hardened should be CCed on this. Compiling with the default hardened gcc-4.4.4-r2 causes all versions of ghostscript-gpl to segfault pretty much immediately. Switching to vanilla gcc and recompiling is a temporary workaround.
More info: this problem only seems to affect x86, and not amd64. Haven't tested any other arches.
A little more experimentation and help from Zorry has shown the problem to be the combination of PIE and -fomit-frame-pointer in CFLAGS. The suggested fix is to remove -fomit-frame-pointer from CFLAGS; it apparently doesn't play nicely with PIE in some cases.
I'm having the same issue, also hardened on x86. Following your comments, I expected that adding this line to the src_compile function before the emake call would fix the problem: use x86 && gcc-specs-pie && filter-flags -fomit-frame-pointer This is not the case, though. After emerging the modified ebuild, I still get: $ gs Segmentation fault
Created attachment 257681 [details] Output of emerge --info
Placing the mentioned line in the pkg_setup function instead solves to problem.
Created attachment 257686 [details] modified ebuild which disables -fomit-frame-pointer on hardened profiles The attached ebuild solves the problem by disabling -fomit-frame-pointer on x86 builds with PIE enabled.
@hardened: what do you think / advise? Is this still happening with current ghostscript-gpl-9.04-r5 ?
It looks OK now. We still have the server that had this problem, and I just now compiled ghostscript on it with -fomit-frame-pointer and PIE: CFLAGS="-march=native -O2 -pipe -fomit-frame-pointer" emerge -1 libpaper ghostscript-gpl ... # gs GPL Ghostscript 9.04 (2011-08-05) Copyright (C) 2011 Artifex Software, Inc.
