Anyone else running into assert building for release

Hello,

Running into an issue trying to build my project in release config (works fine in debug). Anyone run into this, or have suggestions for workarounds/ places to look in my code to build a make a reproducible sample?

Assertion failed: Buffer.empty() && "didn't claim all values out of buffer", file C:\Users\swift-ci\jenkins\workspace\swift-main-windows-toolchain\llvm-project\llvm\..\clang\include\clang/CodeGen/ConstantInitBuilder.h, line 75

Thanks,
mike

I'm totally stuck here... does anyone have any ideas? The build logs (even with -vv) don't offer any clues. I'd love to pare this down to an easily reproducible sample, but I don't even know where to start looking.

Right now this is blocking a release for us.
