Bug ID: 51611
Summary: Crash in LinkageComputer::getLVForDecl
Product: clang
Version: trunk
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs

Clang keeps crashing and told me to file a bug report. I am using emscripten
and c++ modules and was trying to compile some of the code from this
repository: https://github.com/justinhj/astar-algorithm-cpp
I am unfamiliar with the inner workings of LLVM, but I am happy to compile a
debug build or something if it helps.
clang version 14.0.0 (https://github.com/llvm/llvm-project
