[Bug other/31282] SegV on AIX 5.3 due to uninit'ed static object when using -pthread

That does indeed appear to have been the problem.  Even though the system
claims that APAR was already applied, the header file was still missing the
typedef keyword. I suspect something silly like the compiler being reinstalled
after the patch was applied the first time.

Many thanks!

BTW - This also explains a number of other issues I've seen people report with
duplicate symbols for 'thread_creds_t', but this is the only item that search
turned up in the bug DB that mentions APAR IY90737.

Compiling with -pthread adds -D_THREAD_SAFE to the defined macros, which causes
different header files to be included.  Prior to GCC 4.3, this appears to cause
a non-unique name to be chosen for the global constructor in the file.  When
compiling with -pthread, the first global object seen is:

struct thread_credentials {
 uint flags;
 cred_ext_t cred;
 int reserved[9];
} thread_creds_t;

in /usr/include/sys/thread.h

Andrew Pinski pointed out that this is known with a workaround:

According to IBM, the fix for this APAR IY90737 is incorporated into
Service Pack 5300-05-04.

Do you have that installed?
