The cause of the crash is the signal handler, in particular
SIGSEGV in the sigs[] array Top/csound.c:910

The flags for `csoundInitialize' are in csound.h:286

  #define CSOUNDINIT_NO_SIGNAL_HANDLER  1
  #define CSOUNDINIT_NO_ATEXIT          2

so `csoundInitialize(argc, argv, CSOUNDINIT_NO_SIGNAL_HANDLER)`
resolves your problem.
