9.3 is not working (9.2 is also not working after reinstall)

[tbirkandan]

First of all, thanks for the Windows installer. That is a great piece of work!

I am a Windows user and I have been using SageMath 9.2 with no problems. After the release of 9.3, I uninstalled 9.2 and installed 9.3 but it did not work. It shows the first (version number, etc.) lines and closes itself.

Anyway, I was happy with 9.2 and tried to reinstall 9.2 by uninstalling 9.3 but it is not working now. I am enclosing the crash report. Do you have any suggestions? (I do not know if it causes any interference but I also have a VirtualBox and SageMath 9.3 installed on Linux.)

Thank you for the crash report. This looks like a recurrence of #53 which was resolved with a new build. Not sure why it's happening again with the 9.3 build. I don't know when I'll have time to make a new build. But if you reinstall 9.2 make sure it's this release and not the previous one that had the same problem.

Great! It turns out that I was using v0.6.1, and v0.6.2 for SageMath 9.2 solved my problem. Thank you!

Reopening since the issue since it appears the 9.3 build was still plagued by this issue as well (which I'm a bit surprised by).

Hi,

I get this SIGILL too with version 9.3, but I don't have any stacktrace giving me which call crash. This happens with both SageMath 9.3 and python 3 notebooks.
Is there a way to get the clean stacktrace as the OP did ?
How can I guess this ?

I found I get a crash with just this too:

$ sage -python
Python 3.7.10 (default, May  5 2021, 11:43:58)
[GCC 10.2.0] on cygwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy as np
Illegal instruction (core dumped)

Is there some CPU extensions required ?

The same commands won't crash with 0.6.2/SageMath 9.2

@amurzeau Thank you--I wouldn't worry about the details, as it's already a known issue (though it's pretty surprising in your case you got it just from importing numpy)
