--- Comment #4 from Jeffrey Armstrong <jeffrey.armstrong at approximatrix dot com> --- > AFAICT you get the internal error only with compilers configured with > --enable-checking=yes. I was refering to a compiler crash occurring on a non-trivial program: internal compiler error: in convert_move, at expr.c:268 libbacktrace could not find executable to open Please submit a full bug report, with preprocessed source if appropriate. See <...> for instructions. Error(E42): Last command making (build\pn432x.o) returned a bad status Error(E02): Make execution terminated The trivial example I provided does not crash the compiler, but the gcc_assert() at expr.c:268 seems to trigger an ICE under non-trivial conditions. I can try to work up an example that causes the ICE, but I can't provide the source code to the particular file.
