Description Alfred Wingate 2023-08-20 13:12:26 UTC

Building dev-libs/boost on an llvm system produces an ICE from the compiler.

Reproducible: Always

Steps to Reproduce:
1.Try to build boost with clang-17.0.0_rc2
Actual Results:  
ICE

Expected Results:  
It builds fine

clang++: /usr/lib/llvm/17/include/llvm/Support/Casting.h:578: decltype(auto) llvm::cast(From *) [To = clang::CXXConstructExpr, From = clang::Expr]: Assertion `isa<To>(Val) && "cast<Ty>() argument of incompatible type!"' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.

The assertion is only hit when debug use flag is enabled in clang.

Comment 7 tt_1 2023-12-17 12:15:15 UTC

there seems to be some kind of progress in one of the linked pullrequests (39319), you might want to revisit and test for backportability of the fix.

I don't really consider USE=debug a priority and I don't see it as worthwhile unless it's trivial to backport, and even then... 

Does this really matter that much to you? If so, why?
