Hi All, I am using a linux(2.4.16) on mips (bigendian) box for development of gdb tool.Recently I downloaded gdb 5.1 source code and was able to successfully configure and compile for the above mentioned mips box.I am also encountering the same old problem of debugging the threaded application... Starting program: /data/gdb/./SimpleVideolin.out [New Thread 1024 (LWP 438)] Program received signal SIGTRAP, Trace/breakpoint trap. [Switching to Thread 1024 (LWP 438)] 0x00000000 in ?? () In one of the mailing list I saw that this due to bug in libc. Can you tell me 1.Where can find the libc which don't have this bug 2.Is there any patches are associated with gdb for above mentioned problem Thankx for your time... Bino Mathew
