I am making a build2 package of the Range-V3 library (it'll end up in the main repo when it's ready to be published. One of the test source files seems to ICE clang-10 on Windows systematically. See below the dash-line the complete verbose log of build2 compiling that file, with the compiler invokations and output. The crash report is at the end.

The file that generates the ICE: https://github.com/Klaim/range-v3/blob/klaim/build2/test/iterator/basic_iterator.cpp

Notes:

• Same issue with C++17 and C++20. C++14 will generate a valid error.
• Reproduced systematically on Windows 10, this is clang-10 front-end with msvc's backend (see section "Clang Targeting MSVC" in https://build2.org/build2/doc/build2-build-system-manual.xhtml#cc-clang).
• Not reproduced on Linux/Ubuntu 18.04.4 with clang-10 or gcc-10.
• I didn't try with clang-cl because it is not well supported by build2 for now (see the previous link).
• I didn't try with another build system but you can see it doens't seem like the issue comes from the flag set (but I'm not a specialist).

If you have build2 installed and want to reproduce this with it:

• clone this repository: https://github.com/Klaim/range-v3/
• in the cloned directory: b "test/exe{test.iterator.basic_iterator} config.cxx=clang++-10 config.c=clang-10" (or whatever name you gave to clang-10 on your Windows)

I added the proper attachments suggested by the ICE report.
