Some tests are sometime infinite or failing

Some tests are (sometimes) failing on my laptop, i.e., I have to rerun ctest multiple times to get a 100% pass. For these few example below, the behavior is undefined : either pass (~50% times) or segfaults or never finishes. Typically : ***Exception: Illegal or Subprocess aborted***Exception. Some test that I've seen fail (may be non exhaustive)

Delaunay_complex_Epeck_dynamic_test_unit
Weighted_periodic_alpha_complex_3d_test_unit
Zero_weighted_alpha_complex_static_test_unit
Periodic_alpha_complex_3d_test_unit

My specs :

Software My compiler (clang 15.0.7), boost, tbb, cgal (5.6), python libraries and everything else come from the conda-forge repo. And the c++ compiler used is the c++ compiler provided by the compilers package (what is used to compile every conda-forge package).
Hardware M1 macbook air, on Ventura 13.5.2

As cgal was recently updated to the 5.6 version, and the error are all linked to alpha triangulation, my first guess would be in that direction.

Not really useful log :

To try to reproduce, I connected to the public machine gcc104.fsffrance.org (cpu M1, MacOSX 12.6), installed mambaforge and a bunch of packages

Did a (recursive) git clone of gudhi-devel, created a subdirectory build/, cmake -DCMAKE_BUILD_TYPE=Release .., make -j4, make -j4 test, and all the tests (including the 4 you mention) pass. I re-ran the last command a few times, but the tests always pass. The weighted-periodic one takes ~8s, by far the longest. CMake shows

The OSX version is not the same, and the cmake outputs have a surprising number of seemingly minor differences, but I don't immediately see what may explain the different behavior on your computer.

Some tests are sometime infinite or failing #961
