Find the following code in file 'mtype.d' at line 4561:
bool overflow = false;if (mulu(tbn.size(loc), d2, overflow) >= 0x1000000 || overflow) // put a 'reasonable' limit on it
goto Loverflow; And change it to: bool overflow = false; mulu(tbn.size(loc), d2, overflow); if (overflow) goto Loverflow; I would make a PR if I had the time (anyone?)...
