I'll check that in a second. But the gdb thing seems like a bug:

I create a new wxWidgets project, compile it, run it, no problems. Then goto debug->start and it brings up the wxWidgets sample app main window. When I close that gdb does not exit. It's in an endless loop:

The unknown exception problem definately has something to do with the codeblocks default.conf parsing. It's very repeatable:

1. delete default.conf
2. select gcc as default compiler again, turn off tips on startup
3. settings->debugger->enable display debugger log
4. close cb
5. open cb
6. no problems yet
7. close cb
8. open cb
9. not problems yet (??? odd)
10. close cb
11. open cb = unhandled exception
12. open cb = unhandled exception
...

If I leave the unhandled exception dialog box open long enough, dr mingw pops up, but only gives:

Jumped the gun, finally it produced a .rpt:

Haha that's the same place (function) mine was crashing, only mine didn't give a line number I don't think!

grv575:
OK traced the bug by comparing default.conf files at various stages.

A default conf file with these lines does not load (gives the exception):

--- Code: --- <main_frame>
<layout>
<TOOLBAR_SHOW bool="1" />
<LEFT_BLOCK_SELECTION int="0" />
<BOTTOM_BLOCK_SELECTION int="0" />
<MAXIMIZED bool="1" />
</layout>
<LAYOUT>
<bin crc="0">FQAAAHd4RG9ja2luZy1TdHJlYW0tdjEuMAgAAAA8bGF5b3V0PgIAAAAFAAAAZnJhbWVAAAAAQAAAAMgAAAA2AgAAAAEAAAAACAAAAExlZnRIb3N0AgAAAGQxYAAAAGAAAAAYAwAAlgAAAAABAAAAAAoAAABCb3R0b21Ib3N0BAAAAAcAAABUb3BIb3N0lgAAAAAAAAAAAAAACgAAAEJvdHRvbUhvc3SWAAAAAAAAAAEAAAACAAAAZDEIAAAATGVmdEhvc3TIAAAAAAAAAAEAAAAFAAAAZnJhbWUJAAAAUmlnaHRIb3N0yAAAAAAAAAAAAAAAFgAAAHd4U2xpZGVCYXItU3RyZWFtLXYxLjABAAAAAAgAAAA8bGF5b3V0PgMAAAAEAAAATWFpbgEIAAAAQ29tcGlsZXIBCAAAAERlYnVnZ2VyAQ==</bin>
</LAYOUT>
</main_frame>

--- End code ---

Note the crc of 0. If I change that one line to:

--- Code: --- <bin crc="2111425552">FQAAAHd4RG9ja2luZy1TdHJlYW0tdjEuMAgAAAA8bGF5b3V0PgIAAAAFAAAAZnJhbWVAAAAAQAAAAMgAAAA2AgAAAAEAAAAACAAAAExlZnRIb3N0AgAAAGQxYAAAAGAAAAAYAwAAlgAAAAABAAAAAAoAAABCb3R0b21Ib3N0BAAAAAcAAABUb3BIb3N0lgAAAAAAAAAAAAAACgAAAEJvdHRvbUhvc3SWAAAAAAAAAAEAAAACAAAAZDEIAAAATGVmdEhvc3TIAAAAAAAAAAEAAAAFAAAAZnJhbWUJAAAAUmlnaHRIb3N0yAAAAAAAAAAAAAAAFgAAAHd4U2xpZGVCYXItU3RyZWFtLXYxLjABAAAAAAgAAAA8bGF5b3V0PgMAAAAEAAAATWFpbgEIAAAAQ29tcGlsZXIBCAAAAERlYnVnZ2VyAQ==</bin>

--- End code ---

Which is the value it had previously, then it load up again fine. But on shutdown it again puts a 0 for the crc. This is the only difference that makes it crash vs not. Looks like something wrong with the crc calculation not getting run or...?

280Z28:
It's obvious. Unchecked pointer.

--- Code: ---if(!m_pNotebook) return 0;

--- End code ---
