[issue18227] Use Python memory allocators in external libraries like zlib or OpenSSL

[STINNER Victor]

STINNER Victor added the comment:

It looks like CRYPTO_set_mem_functions() of OpenSSL 1.0.1e-4.fc18 does not work: CRYPTO_set_mem_functions() calls indirectly CRYPTO_malloc() which sets "allow_customize = 0;" and so CRYPTO_set_mem_functions() does nothing (just return 0, instead of 1).

Gdb trace with a modified _ssl module:
