Full stacktrace, including u8 symbols (missing in the automatic
retrace).
Unity seems fine actually, but crash happens when calling
pam_authenticate where the pamHandle is something like:
{authtok = 0x7fb300000000 <error: Cannot access memory at address
0x7fb300000000>,
caller_is = 3944807584, pam_conversation = 0xffffffff, oldauthtok = 0x0,

Not sure if it might be a threading issue
