You must break on `_d_throwc` (windows), `_d_throwdwarf` (linux), 
`_d_throw_exception` (ldc).

They are defined in

- https://github.com/dlang/dmd/blob/master/druntime/src/rt/deh.d
- 
https://github.com/dlang/dmd/blob/master/druntime/src/rt/deh_win32.d
- 
https://github.com/dlang/dmd/blob/master/druntime/src/rt/deh_win64_posix.d

At least this is what is done for the Dexed GDB widget, so that 
gdb breaks automatically when an Error or an Exception is new'd 
(https://gitlab.com/basile.b/dexed/-/blob/master/src/u_gdb.pas#L2072).
