This question is not appropriate for the mailing list
g...@gcc.gnu.org. It would be appropriate for gcc-h...@gcc.gnu.org.
Please take any followups to gcc-help. Thanks.
gcc 3.2 is quite old. The C++ parser was completely rewritten in gcc
3.4 to improve correctness. It is quite likely that this is simply a
bug in gcc 3.2. You can probably avoid the bug by using temporary
variables.
