opened on Dec 11, 2023

When running the following on trunk (3d11728)

test.sh

clang++-18 -cc1 -std=c++17 -emit-pch -o qminimalintegration.cpp.oclango qminimalintegration.cpp
clang++-18 -cc1 -x c++ -ast-merge qminimalintegration.cpp.oclango /dev/null -ast-dump-all=json

qminimalintegration.cpp

template <typename _Tp> struct is_object {};
template <typename _Tp, typename... _Args> struct __is_constructible_impl {};
;
static void __attribute__(())
_movdir64b(void *__dst __attribute__((align_value(64))));

The second command crashes with this backtrace

clang++-18: /data/llvm-project/clang/lib/Basic/SourceManager.cpp:865: clang::FileID clang::SourceManager::getFileIDLoaded(clang::SourceLocation::UIntTy) const: Assertion `0 && "Invalid SLocOffset or bad function choice"' 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.

Removing the line with just a semicolon causes a segmentation fault instead.

I found these similar closed issues #31270 and #22247 while checking for duplicates but they looks unrelated to ASTImporter.

CC @jcsxky and @balazske since you've been involved in the other ASTImporter issues, lmk if the CC is unwanted and I wont do it in the future
