Heap problems with 3.8.0rc2 in combination with vs2015 sp1
I made the llvm::Function() constructor public (for testing purpose) and
used the non-overloaded new.
auto func = ::new llvm::Function(...)
if (func) func->eraseFromParent();
And the heap corruption is gone! Did something changed in llvm::User::new
between 3.7.1 and 3.8.0 ?
I found a bug in llvm ?
