Traceback (most recent call first):
File "xxx", line xxx in <xxx>

This function is written for debug purpose only, to dump the traceback in
the worst case: after a segmentation fault, at fatal error, etc. That's why,
it is very limited. Strings are truncated to 100 characters and encoded to
ASCII with backslashreplace. It doesn't write the source code, only the
function name, filename and line number of each frame. Write only the first
100 frames: if the traceback is truncated, write the line " ...".
This function is signal safe. */

This function is written for debug purpose only. It calls
_Py_DumpTraceback() for each thread, and so has the same limitations. It
only write the traceback of the first 100 threads: write "..." if there are
more threads.
If current_tstate is NULL, the function tries to get the Python thread state
of the current thread. It is not an error if the function is unable to get
the current Python thread state.
If interp is NULL, the function tries to get the interpreter state from
the current Python thread state, or from
_PyGILState_GetInterpreterStateUnsafe() in last resort.
It is better to pass NULL to interp and current_tstate, the function tries
different options to retrieve this information.
This function is signal safe. */
