Hi all, 

when I use gdb to debug a multithread program like the following:

(gdb) inf thr
  4 Thread 2051 (LWP 14625)  0x420292e5 in sigsuspend () from /lib/i686/libc.so.6
* 3 Thread 1026 (LWP 14624)  sch_hd_core (arg=0x8ac60f8) at schrun.cpp:221
  2 Thread 2049 (LWP 14623)  0x420e0037 in poll () from /lib/i686/libc.so.6
  1 Thread 1024 (LWP 14619)  0x420b4b31 in nanosleep () from /lib/i686/libc.so.6

(gdb) n
221             memset(&req4sch,0,sizeof(req4sch));

and when I use the command "next", the thread 3 can not go on, but if I change the current 
thread to thread 4 and use the command "next", the thread 3 and 4 can go on. 

can anybody tell me the reason of this??Thanks.

Regards,
Booby Chen

What do you mean by "can not go on"?
