- With latest versions of glibc, a lot of apps failed on a PaX enabled
- system with:
- cannot enable executable stack as shared object requires: Permission denied
-
- This is due to PaX 'exec-protecting' the stack, and ld.so then trying
- to make the stack executable due to some libraries not containing the
- PT_GNU_STACK section. Bug #32960. <azarah@gentoo.org> (12 Nov 2003).
-
- Patch also NPTL. Bug #116086. <kevquinn@gentoo.org> (20 Dec 2005).
