Looking again at the JPEG code here. As far as I can tell setjmp/longjmp have been used with appropriate care, but I worry what will happen if a method on a Device throws an exception, for example. I've had both Visual C++ 2008 and Apple's g++ 4.0.1 crash on me in this kind of situation.
Did you use -fexceptions with GCC, and if I'm not mistaken MSVC also has an option to assume that C functions don't throw exceptions, which shouldn't be used for exceptions to work.
I suspect that -fexceptions was not in play but it's conceivable that our build system adds it automatically when compiling C. I'll double check when I'm at work tomorrow.
If I'm not mistaken, the default for GCC is to assume C functions can't emit exceptions, -fexceptions tells it that they could. A few C libs seem to be compatible with this setup, for example with libpng I register an error callback function which throws, and it works fine but only if -fexceptions is used.
