Actually, I looked into this and alloca is not standard C++ since it can 
create problems for the exception handling (although it compiles fine 
with Visual C). This is probably why there have been compilation 
problems on some platforms (see 
http://mail.cs.uiuc.edu/pipermail/llvmdev/2004-September/001992.html) -- 
A better alternative is maybe to use the std::vector instead of a VLA.
