@alanjt Got the same exact test failures as you when I was building CLAPACK 3.2.1 32-bit static debug libraries using the source with CMake config. I looked at the CMake test log and all the failures seem to be due to a stack overflow.

Steps to reproduce:

1. cd into clapack-3.2.1-CMAKE top-level dir
2. Build: cmake -S . -B build_windows_x86 -A Win32 && cmake --build build_windows_x86 --config Debug
3. Test: ctest --test-dir build_windows_x86 -C Debug

Note that this also produces the same test failures when building for 64-bit as well. Compiler is Visual Studio 2019.

We probably should bring this up to the LAPACK mailing list or the official GitHub repo for Netlib LAPACK. At the same time, however, it's probably better to use LAPACKE over CLAPACK when possible. CLAPACK has not been updated in a while and LAPACKE, which provides a more natural C interface to LAPACK, is the preferred way to use LAPACK from C nowadays.

Update: Also reproduced with Visual Studio 2022 on a different Windows 10 machine.

Anyways, I have filed an official issue in the Netlib LAPACK repo and did some digging to see if I could fix the issue.

Turns out 12 MB seems to be sufficient stack space to reserve for each test program, which can be specified to the MSVC linker via the /STACK parameter, e.g. with /STACK:12000000. I think in the past the CLAPACK folks ran into this issue before as the following lines from TESTING/CMakeLists.txt show that there was an attempt to increase the stack size reserved:

clapack/TESTING/CMakeLists.txt

Lines 1 to 6 in 543e60b

	if(MSVC_VERSION)
	# string(REPLACE "/STACK:10000000" "/STACK:900000000000000000"
	# CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS}")
	string(REGEX REPLACE "(.*)/STACK:(.*) (.*)" "\\1/STACK:900000000000000000 \\3"
	CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS}")
	endif()

This is ineffective, however, as at least for Visual Studio 2019 and Visual Studio 2022 I tried, no /STACK parameter is passed to the linker by default. It's easy to fix this, however, by just modifying CMAKE_EXE_LINKER_FLAGS, i.e. replace above with

if(MSVC)
  set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} /STACK:12000000")
endif()

At least for me this worked and all the tests reporting stack overflow pass now.
