Bug#427990: glibc: PIE executables core dumps on hppa
Package: glibc
Severity: important
Tags: patch
start.S file is messing up the paramaters when using the -pie option.
This causes instant segfault on hppa when trying to run an pie executable.
This causes portmap and nscd to break on this arch and maybe many other
executables.
Here is a patch that fix the start problem, but all pie programs must
be relinked to fix the segfault.
