#### 15.4.10.6 Ada Exceptions

A command is provided to list all Ada exceptions:

`info exceptions`
`info exceptions regexp`

  The `info exceptions` command 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.
