I didn't dig any deeper then what I have written already for icu as we 
have another test case provided in bug 151832. Basically gcc shouldn't 
inline the function or at least provide a callable symbol because its 
address is used later on (in the same file, even), which is what we 
found in the gcc documentation but not in the code ;)

So yes, it IS a toolchain-bug, but one the gcc-4.1 users share (gcc 3.4 
works correctly apparently) :D
