The reverse-finish command results in an internal error if it cannot determine the current function. (gdb) c Continuing. Program received signal SIGSEGV, Segmentation fault. 0x0000000000000000 in ?? () (gdb) reverse-finish Run back to call of #0 0x0000000000000000 in ?? () gdb/infcmd.c:1576: internal-error: Finish: couldn't find function. A problem internal to GDB has been detected, further debugging may prove unreliable. Quit this debugging session? (y or n) y This is not an internal error case since the command may be used in scenarios where there is no function at the current PC, e.g. after calling through a bad function pointer. Turn this into a normal error. gdb/ * infcmd.c (finish_backward): Turn internal error into normal error. testsuite/ * gdb.btrace/segv.c: New. * gdb.btrace/segv.exp: New.
