Bug 807007 – sys-devel/clang-12.0.0-r1 or sys-devel/llvm-12.0.1: sanitizer reports error in DWARF tables of produced binaries

• Product: Gentoo Linux
• Status: RESOLVED UPSTREAM

[Description a.b 2021-08-07 14:27:18 UTC]

Created attachment 731206 [details]
sample code that produces the error

It looks like the clang build of my gentoo is partially broken. I have been told that the error doesn't happen on another distro with same clang version.

The following error message shows up when building with clang++ the provided C++ code with address sanitizer enabled:

error: address range table at offset 0x3bc70 has a premature terminator entry at offset 0x3bc80

Error triggered by: https://github.com/llvm/llvm-project/blob/main/llvm/lib/DebugInfo/DWARF/DWARFDebugArangeSet.cpp#L148

---

Reproduction:

1. compile the attached code with clang++-12 -fsanitize=address -std=c++17 -lSDL2
2. execute the produced executable and look for an error: 2>&1 | grep error

This would be something to report upstream. We don't do anything special at that sort of level.
