"terminate called after throwing an instance of 'std::out_of_range'" crash when compiling with Static Linux SDK #86149
Description
Description
When compiling with the Static Linux SDK, attempting to import statfs (which exists as both a function, and a struct definition in C), the compiler crashes with terminate called after throwing an instance of 'std::out_of_range.
Reproduction
Package.swift:
/ swift-tools-version: 6.2
// The swift-tools-version declares the minimum version of Swift required to build this package.

Expected behavior
Compiler compiles code as expected (as happens when running swift build not using the Static Linux SDK).
Environment
$ swift --version
Swift version 6.2.3 (swift-6.2.3-RELEASE)
Target: x86_64-unknown-linux-gnu
