Well, some progress, here is my current code:
#include <python2.4/Python.h>
#include <python2.4/frameobject.h>
extern "C" void wxFatalSignalHandler(wxTYPE_SA_HANDLER)
{
if ( wxTheApp ) {
PyInterpreterState *interp = PyInterpreterState_Head();
PyThreadState *st;
int threadNum = 0;
for (st = interp->tstate_head; st; st = st->next) {
PyTracebackObject *tb;
PyFrameObject *frm;
fprintf(stderr, "Thread %u:\n", ++threadNum);
st->curexc_traceback = NULL;
for (frm = st->frame; frm; frm = frm->f_back)
if (PyTraceBack_Here(frm) < 0) { fprintf(stderr, "PyTraceBack_Here failed\n"); break; }
tb = (PyTracebackObject *) st->curexc_traceback;
if (tb == NULL) { fprintf(stderr, "traceback is NULL in wxFatalSignalHandler\n"); continue; }
while (tb) {
fprintf(stderr, " %s line %u: %s\n", PyString_AsString(tb->tb_frame->f_code->co_filename),
tb->tb_lineno, PyString_AsString(tb->tb_frame->f_code->co_name));
tb = tb->tb_next;
}
}
}
}
This assumes just one interpreter is running, for now, which could be made into a loop, and this prints only a rudimentary stack trace, which is fine, if a SEGV occurred, I would say…
