I am getting a crash when I am running SnapPy's https://github.com/3-manifolds/SnapPy test suite against SageMath with the stack trace below. I created several different conda environments, all with python 3.9.9, on Mac OS 11.5.2 x86_64 and it seems to be related to the (cy)pari version. That is, I can fix the crash or recreate the crash by changing the environment with "conda install pari==2.11.4" or "conda install 2.13.2". Those commands change the packages as follows:
added / updated specs: - pari==2.11.4 The following packages will be DOWNGRADED: cypari2 2.1.2-py39hbeebeb8_3 --> 2.1.2-py39he58a9ab_0 cysignals 1.11.2-py39h7972417_0 --> 1.10.3-py39h520947a_0 eclib 20210503-h06317ce_2 --> 20210503-h5af3530_0 giac 1.6.0.47-h3e19eb6_2 --> 1.6.0.47-h5514456_0 lcalc 1.23-he3dd645_1006 --> 1.23-h3e22c04_1004 pari 2.13.2-h491590d_1_pthread --> 2.11.4-h797e938_2 sagelib 9.3-py39hf07016b_5 --> 9.3-py39h2a6771f_4 l also tried Marc Culler's Sage releases (https://github.com/3-manifolds/Sage_macOS/releases), version 9.4 and 9.5 prerelease. The crash didn't happen in either version. I think those use pari 2.13.1 and 2.13.3. Hmmm... I noted that the downgrading that fixed the crash removed "_pthread" from the pari version. So maybe pthread support causes the crash.
