fatal internal error: CHECK(range_.Contains(at)) failed at /tmp/<redacted>/staging/llvm_toolchain/source/llvm-project-82f52d9c42d926e23955b42128abff064825d6c8/flang/lib/Parser/provenance.cpp(474)
```

This looks to be a regression of #77791. 

We are building scipy from commit: `76bf366486b0583dca789823878b80d610eb571b`.  Same behavior on tagged release `1.14.0`. 

The platform is Amazon Linux 2023 (Fedora based). Checked on both x86_64 (AWS Intel Sapphire Rapids) and aarch64 (AWS Graviton4, neoverse-v2).

See attached log:

Tagging @h-vetinari as you're on the front lines with flang and scipy :)
