[New-bugs-announce] [issue29683] _PyCode_SetExtra behaviour wrong on allocation failure and after realloc

[Brian Coleman]

New submission from Brian Coleman:

On PyMem_Malloc failure, _PyCode_SetExtra should set co_extra->ce_size = 0.
On PyMem_Realloc failure, _PyCode_SetExtra should set co_extra->ce_size = 0.
On PyMem_Realloc success, _PyCode_SetExtra should set all unused slots in co_extra->ce_extras to NULL.

I will add a GitHub PR for this shortly.
