Summary: infinite loop in MCAsmLayout::EnsureValid
Product: new-bugs
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P

Hello,
when I compile a source file with clang++, the compilation never stops.
Attaching gdb to clang shows that it is stuck in:
llvm::MCAsmLayout::EnsureValid(llvm::MCFragment const*) const
This is a recent regression (at most 2-3 weeks I guess).
I am not sure what the right way is to proceed. I can provide you with a
preprocessed source file that exhibits this behavior, but it is likely to be
around 1 million lines. It is much harder to produce a reduced testcase than
with a crash.
Since the function has Asm in its name, let me mention this is an x86_64 and I
don't specify any arch/tune.
