Build log using Clang

Hi, I'm building libgdiplus from source, and I recently switched from GCC to Clang, the build goes fine, but at runtime the UI is screwed up. Attached you can find the screenshot of the "Open Database" dialog using libgdiplus compiled with GCC and Clang.

Attached the build log which doesn't show anything particularly bad.

When I close KeePass I get this exception:

Unhandled Exception:
