Hello list,
Hello human,
I have a report from someone, who is trying to use pcscd with libccid
on FreeBSD4.
Backtrace is like this:
(gdb) bt full
#0 0x805b483 in MSGFunctionDemarshall (msgStruct=0xbfadc790,

dwContextIndex = 0
#2 0x280a1334 in _thread_start () from /usr/lib/libc_r.so.4
Anyone got an idea where to debug this further? Where does the
strange data
value might come from?
I do not see what went wrong from the trace you give.
It looks like the code crashed on line 256:
esStr->rv = SCardEstablishContext(esStr->dwScope, 0, 0,
&esStr->phContext);
But I don't know which dereferencing is wrong.
esStr have a not so stupid value: 0xbfadc7b8
can you try (in gdb):
print esStr->dwScope
print esStr->rv
print esStr->phContext
print &esStr->phContext
to see what crashes?
Thanks
