New submission from Daniel Stutzbach <[email protected]>:
By the time _PyUnicode_Init is called and does the following:
/* Init the implementation */
free_list = NULL;
numfree = 0;
free_list is already in use. _PyUnicode_Init clobbers whatever was stored
there, leaking memory.
In Python 2, this was not an issue because no unicode functions were called
prior to initialization. In Python 3, Unicode objects are created when
initializing other types.
I found this using valgrind to search for "definitely lost" memory. I'd like
to fix all of those cases, to make it easier to run valgrind on a regular basis.
I'll upload a patch momentarily.
