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.

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

Thanks for this update!

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.
