1.7 - With latest versions of glibc, a lot of apps failed on a PaX enabled
1.8 - system with:
1.9 - cannot enable executable stack as shared object requires: Permission denied

1.11 - This is due to PaX 'exec-protecting' the stack, and ld.so then trying
1.12 - to make the stack executable due to some libraries not containing the
1.13 - PT_GNU_STACK section. Bug #32960. <azarah@gentoo.org> (12 Nov 2003).
1.14 -
1.15 - Patch also NPTL. Bug #116086. <kevquinn@gentoo.org> (20 Dec 2005).
