Description

Tests that use EXPECT_THROW fail on macOS with Apple Silicon M3. Upon catch the tests segfault (aka bus error on macOS) somewhere in libunwind when encountering the autib instruction.

Steps to Reproduce

1. Compile TRIQS on an M3 Mac
2. ctest -R '^gf_density$'

Expected behavior: No bus error.

Actual behavior: bus error

Additional Information

As a workaround one can configure TRIQS with

$ LDFLAGS=-ld_classic cmake ...

As to why that works I have no idea.

I'm using an M1 Mac and encountered the following issues when installing TRIQS:

The following tests FAILED:
	 30 - h5_file (SIGTRAP)
	 31 - h5_group (SIGTRAP)
	 42 - Py_archive (SIGTRAP)
	 58 - nda_bound_check (SIGTRAP)
	 91 - nda_str_indices (SIGTRAP)
	106 - imtime_ops (SIGTRAP)
	113 - atom_diag_h5 (SIGTRAP)
	141 - fourier_matsubara (SIGTRAP)
	145 - g_tau_mul (SIGTRAP)
	149 - gf_density (SIGTRAP)
	200 - different_moves_mc_np2 (Failed)
	202 - different_moves_mc_np3 (Failed)

	213 - histograms2 (SIGTRAP)
	235 - real_or_complex (SIGTRAP)
	267 - py_bug_tight_binding (SIGTRAP)

LDFLAGS=-ld_classic cmake ... solves the problem too.

A similar thing goes for triqs_nevalinna and LDFLAGS=-ld_classic cmake ... also solves the problem.

I can reproduce the issue on my Mac with an M2 chip if I do the exports as suggested in Step 7 in the docs. It seems to be an issue of the Xcode version, since they introduced a new linker with Xcode 15 (see here).

I don't really understand what the problem is but the following works for me (assuming the exports in Step 7 have been done):

• Use the old linker, i.e.

export LDFLAGS=-ld_classic
cmake ...

• Use the default (new) linker but unset LIBRARY_PATH, i.e.

unset LIBRARY_PATH
cmake ...

• Use the default (new) linker together with llvm's libc++, i.e.

export LDFLAGS="-L$(brew --prefix)/opt/llvm/lib/c++ -Wl,-rpath,$(brew --prefix)/opt/llvm/lib/c++"
cmake ...

-ld_classic will be deprecated and removed in future Xcode versions (see here). Maybe we should advertise the third option?
