[PeterBindels-TomTom]

Trying to compile a relatively small TU resulted in this ICE. Have not tried Clang 13/14.

crash.zip - contains script and preprocessed source as requested below.

PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash backtrace, preprocessed source, and associated run script.

Likely a duplicate of #47937 (aka https://bugs.llvm.org/show_bug.cgi?id=48593), which was fixed in d4a8c73.

Since the release/12.x branch is no longer maintained, you'll have to ask the provider of your clang 12 package to apply that patch manually, or use a more recent version of clang.
