radiusclient thread-safety

[Alex Massover]

Hi,

Here's what I get with latest code from CVS:

Program terminated with signal 11, Segmentation fault.
#0  0xb762fd19 in strncpy () from /lib/i686/cmov/libc.so.6
(gdb) bt

#11 0xb768b27e in clone () from /lib/i686/cmov/libc.so.6
(gdb) quit

And the strange thing is that sometimes (rarely) it works, exactly the same code.

Compiled with CFLAGS="-pthread -D_REENTRANT -fstack-protector-all"



Or 

#0  0xb75f19cb in strlen () from /lib/i686/cmov/libc.so.6
