in the case where paster exits without printing any error messages, it
is due to a segfault. i ran paster with strace, and here are the lines
right before it exits:
[{WIFSIGNALED(s) && WTERMSIG(s) == SIGSEGV}], 0) = 3928
--- SIGCHLD (Child exited) @ 0 (0) ---
rt_sigaction(SIGINT, {SIG_DFL, [], 0}, {0x810fde0, [], 0}, 8) = 0
rt_sigaction(SIGTERM, {SIG_DFL, [], 0}, {0x810fde0, [], 0}, 8) = 0
exit_group(0) = ?
