3rd attempt to post the link:

Anyway, my link points to my comment:


PyMem_Free(m_obj->tagname) is called below without holding the GIL: that's illegal. Other move the call to free when the GIL is hold again, or use PyMem_RawFree().

"Warning: The GIL must be held when using these functions. "

Note: You can use PYTHONMALLOC=debug or -X dev to reproduce the issue on a Python compiled in release mode.

On the #ifdef MS_WINDOWS path of mmap_object_dealloc().
