| Recently, I migrated a long-running suite of applications from CodeWarrior to Xcode so as to create universal binaries. The applications are 32-bit Carbon applications. The Intel-native versions perform as expected, including on Snow Leopard. However, the PowerPC version crashes immediately.
EXECUTIVE SUMMARY: I suspect that this error is related to something that's not set up right in my Xcode build and I'd like some help with that.
CRASH ANALYSIS: I can provide the entire crash log if desired. However, what appears to be pertinent here is the following:

The font name passed to GetFNum is (pascal string) "Helvetica".
Note that this CAN'T be fundamentally an API problem, even though the API is deprecated. The crash occurs on a G4 PowerPC running 10.4.11, but SUCCEEDS on an Intel-based iMac running 10.6.6.
So my suspicion is that there is something I'm doing wrong in the Xcode build.
Xcode SETUP: The Xcode project is set up as a standard universal application, with the following custom settings under Xcode 3.2.3 (running on OS X 10.6.6): Architectures 32-bit Universal Base SDK (PowerPC) Mac OS X 10.4 C/C++ Compiler Version GCC 4.0 Mac OS X Deployment Target Mac OS X 10.4
I suspect that I've missed something important here, but I have no idea what that might be.
Can anyone help? I'd be happy to send more information if it is needed; please just let me know what you want to see.
Cheers,

"Cowardice asks the question, 'Is it safe?' Expediency asks the question, 'Is it politic?' Vanity asks the question, 'Is it popular?' But, conscience asks the question, 'Is it right?' And there comes a time when one must take a position that is neither safe, nor politic, nor popular but one must take it because one's conscience tells one that it is right." -Martin Luther King, Jr. (1929-1968)
"The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom." -Isaac Asimov (1920-1992) "If in the last few years you haven't discarded a major opinion or acquired a new one, check your pulse. You may be dead." - Gelett Burgess (1866-1951)
