Hi, I am using g++4.1 and I know it is old by I will be glad if you help me with this problem. I get SIGABRT in my program and with gdb, this is my backtrace: Program received signal SIGABRT, Aborted. 0x00007f86d1a2ca75 in raise () from /lib/libc.so.6 (gdb) backtrace #0 0x00007f86d1a2ca75 in raise () from /lib/libc.so.6 #1 0x00007f86d1a305c0 in abort () from /lib/libc.so.6 #2 0x00007f86cb8ff8e5 in __gnu_cxx::__verbose_terminate_handler() () from /home/mahmood/virtual/amd64-linux/sys/lib/libstdc++.so.6 #3 0x00007f86cb8fdd16 in ??

Thanks for any idea. // Naderan *Mahmood;
