OS: Windows NT
Status: NEW
Severity: enhancement

Component: C++

repro
This test case:
// RUN: %clang -cc1 -emit-llvm %s -gcodeview -debug-info-kind=limited
struct a {
~a();
};
template <typename b> struct c : a {
c(void (b::*)());
};
struct B {
virtual void e();
};
c<B> *d() { static c<B> f(&B::e); return &f; }
Generates an assertion when compiling Clang with -DLLVM_ENABLE_ASSERTIONS=ON
inlinable function call in a function with debug info must have a !dbg location
call void @"??1?$c@UB@@@@QEAA@XZ"(%struct.c*
@"?f@?1??d@@YAPEAU?$c@UB@@@@XZ@4U2@A")
fatal error: error in backend: Broken module found, compilation aborted!
>From a distance it seems "!48 = distinct !DISubprogram(name: "`dynamic atexit
destructor for 'f'"" is missing a 'line' entry? (see .ll)
Unless you have time, any suggestions to where should I look?
