Signal #12 is SIGSYS (Illegal system call). That should not be
related to the SIGCHLD manipulations.

Is getcwd() supposed to cause a SIGSYS at all?
OTOH, that failing dlsym() syscall could be related to all this... I
don't know why that complicated dlsym() is used, but maybe since
sigaction() is now invoked directly before, the run-time loader has
already loaded it from libc.so before. Maybe Alexandre can shed some
light on how that's supposed to work.

Never trust an operating system you don't have sources for. ;-)
