Hello,
I'm trying to implement client SSL authentication for Linux [0], but
I'm facing a couple of issues with my current code (patch set >= 3 in
[1]).
The first one is the one in the description, SSL_ClearSessionCache
fails by invalid free (according to valgrind) when closing Chromium if
some successful client authentication has been done during the
execution.
The other one is a segmentation fault that happens sometimes when
reloading a site in which the client was succesfully authenticated
using SSL, it seems to be produced by some sqlite3 method, but I don't
know if I'm provoking it or it's something in the lower layers. Here
is the gdb output:

Maybe both issues are related, could someone give me some light about
those issues?
Thanks.
