A reinstall is probably not necessary. Almost certainly it is because
you're passing hThread to pth_join, which is uninitialized. Try:
hThread = pth_spawn(PTH_ATTR_DEFAULT, clientThread, 0);
if (hThread == NULL) {
.
.
.
/* no need to check - it can't fail! */
pth_join(hThread, (void **)&valuePtr);
You're bizarro handling of valuePtr probably doesn't have anything to do
with your error, but you should probably just declare it as an "int", as
suggested.
