Problems with gcc-4.0.1 libstdc++ and mvme5500



I have been trying to get cexp-1.5/RTEMS-GeSys_2.1.beta running on the MVME5500 with rtems-4.6.99.2. I seem to have run into an issue with the libstdc++ library created by gcc-4.0.1. When I compile RTEMS-GeSys to link in libstdc++ I get an exception 3 on RTEMS startup. The same thing happens if I try running the iostream sample. If I build the same source with the tools for RTEMS-4.6.x, everything seems fine. Both RTEMS-GeSys and iostream run with out the error.

The problem appears to be in a function called _Z41__static_initialization_and_destruction_0ii. Using the excludes in RTEMS-GeSys to exclude parts of libstdc++, it seems that the problem is caused if the bitmap_allocator.o and/or codecvt.o object files are linked.

I found PR712 which refers to similar problems with gcc-3.3.5. Are there any know issues with using gcc 3.x compilers and rtems-4.7 code?
