[clang][crash] Clang crash for wasm target when processing a file using modules on macOS

[Algorithm0]

I am using EMSDK. On versions 4.0.16 and 4.0.17, I see clang crashing on my MacBock on M4 Pro (macOS Tahoe 26.0.1).
I would like to draw your attention to the fact that the same code base with the same configuration compiles perfectly on Linux x86_64 (Fedora Workstation/Ubuntu).
I have included the crash log in the output.log file. Below are the files that I was also asked to send in the event of a crash (I simply couldn't find any files with the mask clang-22_<YYYY-MM-DD-HHMMSS>_<hostname>.crash in the location /Users/aurum/Library/Logs/DiagnosticReports).
