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. -- Andrew I MacIntyre "These thoughts are mine alone..."
