HelloWorld Plugin on Ubuntu 11.04

hibbity:
Following OnExit, the gui app continues to execute into wxEntry(...) and never returns, as illustrated in debugging session:

GNU gdb (Ubuntu/Linaro 7.2-1ubuntu11) 7.2
This GDB was configured as "i686-linux-gnu".

Reading symbols from ../wx_test/bin/Debug/wx_test...done.

<<<File->Quit causes OnExit(), (Thread 14415 has not exited); execution is hung here, no return to gdb command prompt.>>>

I would need to rebuild libwx_baseu-2.8 with debugging symbols to be able to trace into it.

hibbity:
I followed tips found in http://wiki.codeblocks.org/index.php?title=Debugging_with_Code::Blocks
 i.e. compiler build settings (enable debugging symbols), no optimization or symbol stripping.

Then rebuild wxCustomButton, reinstall wxCustomButton, Rebuild test GUI, Debug test GUI.
Result is the same as before.  GUI app uses the same shared library as before.


--- Code: ---0x00840c87 in wxEntry(int&, wchar_t**) () from /usr/lib/libwx_baseu-2.8.so.0
--- End code ---

This should read, "libwx_baseud-2.8.so.0" instead (i.e. the debug version of the shared library).  How do I change it?
