Lev Stipakov commented on TS-4093:
----------------------------------
Crash is caused by calling TSVConnClose inside TS_SSL_CERT_HOOK.
Thanks to gdb watch, turns out that TSVConnClose clears memory at ssl->ex_data
{code}
18:32 < lev__> this is what *ssl contains at the moment of segfault

18:38 < shinrich1> Ok, ssl->ex_data is the issue. ssl->ex_data.sk should not
be null if we had previously called SSL_set_ex_data in make_ssl_connection. So
either that call wasn't made (don't see how that could happen) or something
cleared that value.
