I opened this issue:

  https://github.com/fplll/fplll/issues/432

It might be possible to use GitHub actions to test on ARM.

2020-01-26 Thread 'Martin R. Albrecht' via sage-release
We got some new multicore code in 5.3.x, that seems to trigger it.

2020-01-26 Thread Jaap Spies
Hi Martin,

I'm kind of back to Sage. It's the Raspberry Pi! The actual machine I 
tested sage on, is a Raspberry Pi B4 with 4GB RAM and with the root / 
partition mounted on a WD sdd of 500 GB. Affordable, I think.

Cheers,

Jaap

Hi all,

Sorry, I have no idea about this. But indeed, we never test on ARM. Feel free 
to open an issue on FPLLL’s issue tracker but I’m not sure there’s much we can 
do without a machine to test things on.

Cheers,
Martin
