--- Comment #4 from Hans <sungdgdhtryrt at gmail dot com> ---
Indeed the core file is not necessary to provoke the bug. Here is a minimal
setup for the bug to occur.

cat > main.cpp << EOF
#include <stdio.h>

int main() {
        printf("hello world\n");
        return 0;
}
EOF

clang++-16 -g -gsplit-dwarf -c main.cpp -o main.o
clang++-16 main.o -o main
llvm-dwp-16 -e main -o main.dwp

<path to custom built gdb> ./main

clang++-16 tooling uses dwarf version 5 by default. The "--readnow" option =
is
not necessary.

Thank you again for the hint. I will try to send a gdb patch for this.
