--- Comment #4 from Alexander Lelyakin <alexander.lelyakin at googlemail dot

The ICE in "install entity" can have different stacktrace.
Stacktrace is same up to 'module_state::load_section'
but then it has at least two different variants:
----1
/usr/local/bin/g++ -std=c++20 -fmodules-ts -x c++-system-header memory
/usr/local/bin/g++ -std=c++20 -fmodules-ts -x c++-system-header streambuf
/usr/local/bin/g++ -std=c++20 -fmodules-ts -x c++-system-header regex
