[posixtest-discuss] failure with sigprocmask on IA64 platform

[Xiong, C. <cry...@in...>]

Hi,

I ran a test case for sigprocmask in posixtestsuite project based on =
kernel 2.6.1=20
with libc-2004-02-01 on IA64 platform. The case failed, following is the =
detailed=20
information.

Platform:
--------------------
libc: 2004-02-01
Linux kernel: 2.6.1-mm2 SMP on ia64
gcc-3.3.3-20040209
Redhat EL-3.0-update1

Test Case and Output
----------------------
The case can be found at =
http://cvs.sourceforge.net/viewcvs.py/posixtest/posixtestsuite/conformanc=
e/interfaces/sigprocmask/12-1.c

Output:=20
FAIL: signal mask was changed.

I have also tested it on ia32 platform, it works well. From the strace =
log,=20
signal set is unchanged after calling sigprocmask with invalid =
=A1=B0how=A1=B1, so test
case passes. But when executing the case directly, the case would fail =
with SIGALRM
in the signal set.

The strace log is as the following:
=A1=AD=A1=AD
