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.
