[wxMac only?] Exception sample not working

[H]

Currently I have tested 2.8 branch latest version but I also tested it 
sporadically since 2.7:

Compiling wx with the configuration

./configure --with-mac --enable-debug --enable-unicode 
--disable-universal --disable-monolithic --enable-gui --disable-shared 
--enable-exceptions --without-odbc --with-opengl

entering make and going to the sample folder except and also entering 
make results in a sample that:

 - catches thrown strings -> OK
 - crashes badly when ints and objects are thrown.

Here is the dump:

Exception Type:  EXC_CRASH (SIGABRT)

Does it only crash on Macs or is this a general GCC problem or a bug in 
wxWidgets? BTW: I am using GCC 4.0.1.
