You might want to try running tests/test_vmcircbuf under gdb and see
what happens.
I suspect that you'll see that its getting a SIGSEGV or SIGBUS from
some place below test_factory even though there are properly installed
signal handlers.
See gnuradio-core/src/lib/runtime/gr_local_sighandler.{h,cc} for the signal
handing code.
gnuradio-core/src/lib/runtime/gr_vmcircbuf.cc sets up the sighandlers here:
bool
gr_vmcircbuf_sysconfig::test_factory (gr_vmcircbuf_factory *f, int verbose)
{
// Install local signal handlers for SIGSEGV and SIGBUS.
// If something goes wrong, these signals may be invoked.
gr_local_sighandler sigsegv (SIGSEGV, gr_local_sighandler::throw_signal);
gr_local_sighandler sigbus (SIGBUS, gr_local_sighandler::throw_signal);
try {
return standard_tests (f, verbose);
}
catch (gr_signal &sig){
if (verbose){
fprintf (stderr, "....... %s: %s", f->name (), "Failed\n");
fprintf (stderr,
"gr_vmcircbuf_factory::test_factory (%s): caught %s\n",
f->name (), sig.name().c_str());
return false;
}
}
catch (...){
if (verbose){
fprintf (stderr, "....... %s: %s", f->name (), "Failed\n");
fprintf (stderr,
"gr_vmcircbuf_factory::test_factory (%s): some kind of uncaught
exception\n",
f->name ());
}
return false;
}
}
