However, the specific test that I am looking at, finish-reverse.exp, is not fixed. Here is the list of failures with and without your fix: err file name no patch louise patch gdb.reverse/finish-reverse-bkpt.exp 2 2 gdb.reverse/finish-reverse.exp 11 11 gdb.reverse/fstatat-reverse.exp 1 1 gdb.reverse/next-reverse-bkpt-over-sr.exp 2 2 gdb.reverse/solib-precsave.exp 17 0 gdb.reverse/solib-reverse.exp 17 0 gdb.reverse/step-precsave.exp 7 0 gdb.reverse/step-reverse.exp 7 0 gdb.reverse/until-precsave.exp 2 2 gdb.reverse/until-reverse.exp 1 1 I will look a bit more into what your patch is doing and see if I can understand what is going on in the finish-reverse.exp test with regards to your patch. Thanks for the help. Carl
