No body to blame, if you add "-femit-class-debug-always" option, you get everything expect.

About the performance issue, it is an gdb issue.

And this is not on by default for a reason I suppose.

Yes, but this is because there is too much data.
Can you try to contact the gdb devs to see what is their opinion?

@ollydbg: is value of 'event' correctly displayed in watches window? If not try to cast it to 'wxCommandEvent' (without reference).

If the app link to a wx-release-library, and you does NOT use the "-femit-class-debug-always", then nothing will shown in the watch window.
See log:

--- Code: ---[debug]> whatis event
[debug]type = wxCommandEvent &
[debug]>>>>>>cb_gdb:
[debug]> output event
[debug](wxCommandEvent &) @0x22fb34: <incomplete type>>>>>>>cb_gdb:
--- End code ---

It is already wxCommandEvent, right? See the log previous and also my first post.

The GDB devs already noticed this regression, so they have a bugzilla report: Bug 15412 – Performance regression in "info {func,var,types} foo" (mostly info types).

oBFusCATed:
Then why -femit-class-debug-always is not on by default for C++ code?
