Hi there, I have a problem compiling the following parser with gcc-3.3 in a 64 bit environment: the compiler consumes a lot of cpu time, but never returns. On my old 32 bit box I could compile a similar parser without problems. Also I can compile this parser with gcc-3.3 -m32. With gcc-4.1 I can build a 64 bit version but due to company restrictions I have to use the gcc-3.3. Thanks for any suggestions.
