[Interest] [Qt-interest] Fwd: Application crashes on Mac OS X when loading a pixmap

[Bo Thorsen]

Please read the message again, it's in your own code you have to check 
for crc32. If there is no such symbol, then this isn't the problem.

On some, not all, of the Linux boxes the linker chose to link the global crc32 from the customer code to the function pointer in png, so when the png libary uses the function pointer, it crashes.
