Linux multi-threads

[vincent ribiere <ribiere@cisco.com>]

Hello,

I'm trying to spawn multiple threads (i.e multiple channels) on Linux - Redhat 6.1.
The threads seem to be created OK but when the 2nd thread tries to access lp->args within thread_main
(line 383 in thread_main.c), I get a seg fault on the following line:

VXIObjectSetProperty(lp->args,"telWaitTimeout",VXIFloatCreate(CALL_TIMEOUT));

Did anyone try to create multiple channels ? The fix is hopefully simple but as I'm not used to the
VXIObjects I have some problems tracing things with gdb.

Thanks in advance,

Vincent
