    Hello,

    32-bit Application built on AIX 5.3(with TL08) when to executed on other AIX 5.3 machine (With TL01) return loader error:

    1. oslevel -s
    5300-01-00-0000
    1. ./test
    exec(): 0509-036 Cannot load program ./test because of the following errors:
    0509-130 Symbol resolution failed for test because:
    0509-136 Symbol __pthread (number 7) is not exported from
    dependent module /usr/lib/libpthreads.a(shr_xpg5.o).
    0509-192 Examine .loader section symbols with the
    'dump -Tv' command.

    After running dump on AIX 5.3 machine i don't see the entries for symbol __pthread in /usr/lib/libpthread.a library. on AIX 5.3(TL01) but on TL08 symbol __pthread is exported.

    Any tech alert for this issue ??

    1. dump -Tv /usr/lib/libpthread.a |grep -i __pthread
    [2] 0x00000000 undef ImpExp UA EXTref libpthreads.a(shr_comm.o) __pthread_cleanup_handlerqueue

    but on build machine it is available:

    $ oslevel -s

    $ dump -Tv /usr/lib/libpthread.a |grep -i __pthread
