abhinavgaba noted that commit ce44fe199bbf triggers an assertion failure in
APInt for a very specific case of void pointer math. Reproducer is simple:
$ cat test.c
void a() {
(void *)0 + 0xdead000000000000UL;
}
$ clang -cc1 -triple i386-pc-linux test.c
clang: /localdisk2/gabaabhi/ics/l1/llvm/llvm/lib/Support/APInt.cpp:1609:
llvm::APInt llvm::APInt::udiv(const llvm::APInt&) const: Assertion `RHS.U.VAL
!= 0 && "Divide by zero?"' failed.
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
backtrace, preprocessed source, and associated run script.
Stack dump:
0. Program arguments: clang -cc1 -triple i386-pc-linux test.c
1. test.c:2:35: current parser token ';'
2. test.c:1:10: parsing function body 'a'
3. test.c:1:10: in compound statement ('{}')
