Attaching to a program with multiple threads results in a duplicate listing like below: (gdb) info threads Id Target Id Frame 3 Thread 801406400 (LWP 101466 main) 0x0000000800b648ba in nanosleep () from /lib/libc.so.7 * 2 Thread 801406800 (LWP 100123 otherthread) 0x0000000800b648ba in nanosleep () from /lib/libc.so.7 * 1 Thread 801406800 (LWP 100123 otherthread) 0x0000000800b648ba in nanosleep () from /lib/libc.so.7 Attached the test program used for the above demonstration. I proposed a patch in Bug 201149, but it sounds like jhb@ has a more complete patch. -- You are receiving this mail because: You are the assignee for the bug.
