Do you have possibility of running a debugger on that board or getting a
core dump for remote analysis? I would like to get bit more detailed
information on what exactly is crashing the program and getting a
backtrace or even the current function at the time of the segfault would
be quite helpful.

Well, it is of course possible that a bug that is causing this has been
fixed in 0.6.3, but since I do not have any idea what exactly is
triggering the crash, I don't know how likely it would be for this to be
the case.

If you are using PEAP with Windows XP, you would need to configure a
trusted CA certificate on the client to allow it to authenticate the
authentication server. For a quick, but not really secure, test, you
could temporarily disable the server certificate validation in the
client and see whether that removes this message about the certificate.
