Bug#1063937: glibc: Please add workaround to fix posix_spawn() on sparc64

[John Paul Adrian Glaubitz]

Source: glibc
Version: 2.37-15
Severity: important

Hello,

there is currently a nasty bug on sparc64 that breaks posix_spawn() [1]
and potentially any package that uses gcc since libiberty switched to
using posix_spawn() with gcc-14.

The attached patch comes from Michael Karcher (CC'ed) and unbreaks
posix_spawn() so that gcc works again without posix_spawn() failing
with "Bad Address".

Since this patch is just a workaround and we're not even sure whether
the bug is in the kernel or glibc, it's not been pushed upstream yet.

Adrian
