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.
