[issue23689] Memory leak in Modules/sre_lib.h

[Evgeny Kapun]

Evgeny Kapun added the comment:

This patch doesn't fix the issue. The problem is that the list starting with state->repeat doesn't necessarily contains all repeat contexts that are allocated. Indeed, here [1] and here [2] repeat contexts are temporarily removed from the list. If the match procedure terminates abruptly, they are not added back.
