I have tyhe pthread debug library:
# find / -name "libpth*"
/usr/ccs/lib/inst_updt/libpthdebug.a
/usr/ccs/lib/libp/libpthread.a
/usr/ccs/lib/libp/libpthreads.a
/usr/ccs/lib/libp/libpthreads_compat.a
/usr/ccs/lib/libpthdebug.a <==== here
/usr/ccs/lib/libpthread.a
/usr/ccs/lib/libpthreads.a
/usr/ccs/lib/libpthreads_compat.a
/usr/ccs/lib/libt/libpthread.a
/usr/ccs/lib/libt/libpthreads.a
/usr/ccs/lib/libt/libpthreads_compat.a
/usr/ccs/lib/perf/libpthread.a
/usr/ccs/lib/perf/libpthreads.a
/usr/ccs/lib/perf/libpthreads_compat.a
/usr/lib/libpthdebug.a <==== here
/usr/lib/libpthread.a
/usr/lib/libpthreads.a
/usr/lib/libpthreads_compat.a
#
The tools procstack (from man: Prints the hexadecimal addresses and symbolic
names for all the threads in the process) from ibmprocstack can read the thread:
# ldd /usr/bin/procstack
/usr/bin/procstack needs:
/usr/lib/libc.a(shr_64.o)
/usr/lib/libptools.a(shr64.o)
/unix
/usr/lib/libcrypt.a(shr_64.o)
/usr/lib/libpthreads.a(shr_xpg5_64.o)
/usr/lib/libC.a(shr_64.o)
/usr/lib/libodm.a(shr_64.o)
/usr/lib/libtrace.a(shr_64.o)
/usr/lib/libC.a(shrcore_64.o)
/usr/lib/libC.a(ansicore_64.o)

Below output from procstak:

Does the output from procstak is useful?
How to configure 'configure' or 'make' to use the /usr/lib/libpthdebug.a ?

Thierry
