Andrew Burgess	938f0e2f67	Remove previous frame if an error occurs when computing frame id during unwind. ... https://sourceware.org/ml/gdb-patches/2014-05/msg00712.html If an error is thrown during computing a frame id then the frame is left in existence but without a valid frame id, this will trigger internal errors if/when the frame is later visited (for example in a backtrace). This patch catches errors raised while computing the frame id, and arranges for the new frame, the one without a frame id, to be removed from the linked list of frames. gdb/ChangeLog: * frame.c (remove_prev_frame): New function. (get_prev_frame_if_no_cycle): Create / discard cleanup using remove_prev_frame. gdb/testsuite/ChangeLog: * gdb.arch/amd64-invalid-stack-middle.S: New file. * gdb.arch/amd64-invalid-stack-middle.c: New file. * gdb.arch/amd64-invalid-stack-middle.exp: New file. * gdb.arch/amd64-invalid-stack-top.c: New file. * gdb.arch/amd64-invalid-stack-top.exp: New file.	2014-05-30 22:36:14 +01:00
