Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++

one .cpp, many .h, one .ii
I am trying to compile the included code with this command
x86_64-w64-mingw32-g++.exe -pedantic -Wfatal-errors -Wextra -Wall -std=c++26
-fconcepts-diagnostics-depth=10 -fno-rtti -fno-exceptions -Wno-parentheses
-fopenmp -g -march=native -Wa,-muse-unaligned-vector-move -m64
test_sparse_matrix.cpp
or this
g++ -std=c++26 test_sparse_matrix.cpp
and g++ freezes forever (forever means > 24 hours)
The OS is Windows 11 x64
The g++ -v is:
Using built-in specs.

Because of freeze, I cannot guarantee that my code is compile-time or runtime
correct.
