Created attachment 359565 [details]
Correct x86_64 pselect() call.
Created attachment 359566 [details]
Incorrect ia64 pselect() emulated by glibc.
This is a bug in kernel-headers, it needs to define the syscalls. glibc then just needs to be rebuilt against the fixed kernel-headers and it will magically pick up the syscalls. Created attachment 361518 [details]
RHEL5 fix for this issue
Patch that resolves this issue.
Tested by doing
1. compile reproducer with existing glibc. Test fails.
2. apply patch to tree, and install kernel-headers.
3. rebuild glibc rpms
4. reinstall glibc rpms
5. compile reproducer. Test succeeds:
[root@altix4 tmp]# ./doit
Calling pselect.
Test succeeded.
