If you find any problems on the compiler side please report them, GCC 4.3 will soon go into regression-only mode and be released as stable from there.

The problem we have with gcc-4.3 is most probably the hacky way the QEmu stuff (the recompiler/ directory was originally taken from Qemu and extended) uses the assembler output of gcc. For instance, gcc-4.0 is known to not work as well. This is less a problem of gcc than of using the generated code.

Ah qemu problems I see, upstream qemu still doesn't support gcc4 let alone gcc 4.3.

changing -O3 seems to fix the helper.c compiler ICE with gcc 4.3, see gcc.gnu.org/bugzilla/show_bug.cgi?id=35135

Note that we fixed the source a little bit different. But the file op.c still requires gcc <= 4.2. The configure script detects this correctly and asks for a compatibility compiler.

Finally obsolete since release 2.1.0.
We have fixed some of these problems ourself, some are still to do. Note that we don't support gcc-4.3 yet. That is VBox compiled with this compiler is not supposed to work well. We will not support gcc-4.3 before it is finally released. Currently I'm observing problems in the recompiler.
