The Clang static analyzer crashes when analyzing code that imports C++20 modules **built with coverage instrumentation flags** (`-fprofile-instr-generate -fcoverage-mapping`).
**No external dependencies required** - crashes with just standard library templates.
Environment:
- **Clang version**: 21.1.6 (also affects clang-20)
- **OS**: Linux
- **Standard**: C++26 (also reproducible with C++23)
There is a minimal reproducer attached.
