A command is provided to list all Ada exceptions:
info exceptionscommand allows you to list all Ada exceptions defined within the program being debugged, as well as their addresses. With a regular expression, regexp, as argument, only those exceptions whose names match regexp are listed.
Below is a small example, showing how the command can be used, first without argument, and next with a regular expression passed as an argument.
(gdb) info exceptions All defined Ada exceptions: constraint_error: 0x613da0 program_error: 0x613d20 storage_error: 0x613ce0 tasking_error: 0x613ca0 const.aint_global_e: 0x613b00 (gdb) info exceptions const.aint All Ada exceptions matching regular expression "const.aint": constraint_error: 0x613da0 const.aint_global_e: 0x613b00
It is also possible to ask gdb to stop your program's execution when an exception is raised. For more details, see Set Catchpoints.
