--- Comment #7 from Martin Sebor <msebor at gcc dot gnu.org> --- Created attachment 38274 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=38274&action=edit Patch to replace C++ VLAs with alloca. For future reference, the attached patch gets around the problem by replacing C++ VLAs in libjava with __builtin_alloca(). libjava already uses __builtin_alloca() so the change would be in line with this practice. At the same time, libjava contains C++ throw statements so it seems that it must already link with libsupc++ which provides the required C++ exception support, including the unresolved __cxa_throw_bad_array_length function, so there may be a better solution to the problem than replacing the safer VLAs with the unsafe builtin.
