The pthreads implementation on 4.x (-lc_r) will also provoke a bus error
if the primary thread's stack (which is hard coded at 1MB) is exhausted.

-lc_r linked pthreads programs on 5.x will also behave this way, but I
don't know whether -lkse has the same limitation.

This has become more prevalent with the more profligate stack use by
recent gcc releases.
