gdb 调试任何程序都提示 “Program received signal SIGTRAP, Trace/breakpoint trap.”

 

 (gdb) handle SIGTRAP nostop pass

Program terminated with signal SIGTRAP, Trace/breakpoint trap.

One of the reasons this may happen is when your GDB loads "wrong" libthread_db.so (one that doesn't match the target libc.so.6).
