I read the CodeWarrior groups on Usenet religiously, and I don't 
remember many recent complaints about optimizer bugs.  Most of the 
complaints seem to be about the IDE and debugger, not the compiler.

Fair enough... and since I recently told Roger "test, don't hope", I 
did a quick test, kludging GLTextureManager.c and E3FFR_3DMF_Text.c 
so that they could be compiled with exceptions off.  I built the 
Carbon release CFM version of Quesa with and without exceptions.

Size: with exceptions, 1046K.  Without, 1003K.  About a 4% difference.

Speed: I ran the MultiBox test in Geom Test with both libraries.  If 
anything, it was a tad faster with exceptions, though I can't imagine 
why.  Let's just say the difference was probably within experimental 
error.
