    LLVM is very demanding of the host C++ compiler, and as such tends to expose +bugs in the compiler. In particular, several versions of GCC crash when trying +to compile LLVM. We routinely use GCC 3.3.3 and GCC 3.4.0 and have had success +with them. Other versions of GCC will probably work as well. GCC versions listed +here are known to not work. If you are using one of these versions, please try +to upgrade your GCC to something more recent. If you run into a problem with a +version of GCC not listed here, please let +us know. Please use the "gcc -v" command to find out which version +of GCC you are using. +

    + +

    GCC versions prior to 3.0: GCC 2.96.x and before had several +problems in the STL that effectively prevent it from compiling LLVM. +

    + +

    GCC 3.3.2: This version of GCC suffered from a serious bug which causes it to crash in +the "convert_from_eh_region_ranges_1" GCC function.
