Bug ID: 46274
Summary: Crash when building module "should not perform lookups
into transparent contexts"
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++2a
Assignee: unassignedclangbugs at nondot.org

Archive of the repro files and script
I see there is a similar bug (27186) but it is old and says it is already
fixed, but latest build has repro.
Running the attached archive script ./build-linux causes latest clang++ to
crash.
Linux Build!
clang++: /mnt/d/Repos/llvm-project/clang/lib/AST/DeclBase.cpp:1630:
clang::DeclContext::lookup_result
clang::DeclContext::lookup(clang::DeclarationName) const: Assertion
`getDeclKind() != Decl::LinkageSpec && getDeclKind() != Decl::Export && "should
not perform lookups into transparent contexts"' failed.
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
backtrace, preprocessed source, and associated run script.
