<pre>I found this problem using clang 3.4 and checker-276. I have just checked to
see if the problem still occurs with a trunk build of llvm + clang and it does.
ex.cpp - contains a divide by zero error
int main()
{
int i = 0;
return 1/i;
}
As soon as you try and disable the relevant core checker the static analyzer
asserts
$HOME/llvm-20150112/tools/clang/tools/scan-build/scan-build
--use-analyzer=$HOEM/llvm-20150112-build/Release+Asserts/bin/clang
--use-c++=$HOME/llvm-20150112-build/Release+Asserts/bin/clang -disable-checker
core.DivideZero clang -g -o ex ex.cpp
clang: /vault/home/adrian.swain/llvm-20150112/lib/Support/APInt.cpp:1866:
llvm::APInt llvm::APInt::udiv(const llvm::APInt&) const: Assertion `RHS.VAL !=
0 && "Divide by zero?"' failed.</pre>
