So gdb, just exits. By echoing the exit status I get confirmation that indeed something is wrong: ... $ gdb -q -i dap; echo $? 1 $ ... Only by debugging and doing catch throw do I find out that I'm running into a python exception. It would be nice if gdb would somehow print exceptions. By doing catch catch do I see that indeed exception_print is called in gdb_main: ... 1329 exception_print (gdb_stderr, ex); ... with the exception ex containing the desired message, but that seems to have no visible effect. I tried some obvious-looking things after executing the exception_print, trying to get the printed text to somehow appear: ... (gdb) call (void)fflush (0) (gdb) call gdb_flush (*current_ui_gdb_stderr_ptr ()) (gdb) call gdb_flush (*current_ui_gdb_stdout_ptr ()) (gdb) call (void)fflush (0) ... but no luck. -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread

Previously I had this mode not redirect stderr, but that turned out not to work with the client we're using. There is a logging setting that the test suite uses though. -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread
