Is “syscall-template.S: No such file or directory” a bug of GDB or My Program

Question

I used GDB to debug a combined program of Python and C. The GDB gives me an error when segmentation fault of my program occurs.

81  ../sysdeps/unix/syscall-t         


        

Answer 1

If your program passes invalid arguments to a C library function, it can crash in the C library. And, if you don't have the source for the C library installed, then you will get a message like this from gdb. However, this doesn't mean anything is wrong... it is normal to be missing debuginfo and/or source for one or more libraries used by a program. Ordinarily the solution is to go "up" a few stack frames and see what the real problem is. More rarely you may be encountering a library bug.
