msys2 mingw32 clang++ only fail. msys2 mingw64 clang++ work fine.

This is not a libc++ bug. Your using libstdc++.

To Eric Fiselier

Oh...

Where shold I post report?

Quuxplusone commented 8 years ago

I keep rebinning it as clang. That's where it should be.

Quuxplusone commented 8 years ago 
Hello,
As it looks the reported issue exactly the same as
https://github.com/Alexpux/MINGW-packages/issues/1669

The minimal samples to trigger a crash are:
struct A {
  char ok;
  void init();
  void method() {
    if (ok) init();
  }
};

static A a;
int main() {
  a.method();
}

or

struct _Hashtable {
  void *_M_buckets;
  void _M_deallocate_buckets();
  ~_Hashtable() {
    if (_M_buckets)
      _M_deallocate_buckets();
  }
} a;

Compiled with:
clang -c -O2 sample.cpp

Verbose output as well as some others details are provided on github. Could you
give it a look please?

It looks slightly different. It's seem malloc function work fine.
