2691	Zlib 1.2.5 issues	willimm	bdubbs@…	"These are some issues with Zlib 1.2.5 that I think need fixing:

 * Zlib 1.2.5 segfaults a lot when built with GCC 4.5.0, either while building, or while a program using it is running (IE: with Firefox). The solution: add -mstackrealign to CFLAGS (You need to do this on the configure step, not on the make step), as documented at http://linuxfromscratch.org/pipermail/blfs-support/2010-June/067355.html.
 * Also, when building a shared libary Perl (using -Duseshrplib) on 64bit systems, the Compress::Raw::Zlib module fails because of the module attempting to use the static Zlib, but because it's not compiled with -fPIC, the build fails. To avoid this, -fPIC should be added to CFLAGS, along with -mstackrealign."	defect	closed	normal	6.7	Book	SVN	normal	fixed
