A couple of people have said to me that gcc 4.3.4 is the best of the gcc's. Do the gcc developers have any thoughts on this? I'm only concerned about bugs where the assembly code does not reflect the source code.
According to the 'Serious regressions' criterion, the results available at http://gcc.gnu.org/ suggest that 4.4.2 is the release you are looking for.
But if you are really concerned about wrong-code bugs, you might be best sticking to compilers supported by someone that will fix any bugs you might encounter.
Clearly some releases like gcc 4.0.0 are more buggy than most.
That is one reason why subsequent GCC versions were released. David Daney
