Sorry @hujun260 I think we might have a Race Condition that's intermittently hanging and failing the Signals Test in OSTest. Yesterday Milk-V Duo S SBC (SG2000) tested OK. But today it's hanging: knsh64 fails the Signal Test with a Segmentation Fault (it was OK yesterday): Are you able to reproduce this problem when you re-run knsh64 a few times? Thanks! |

can you reproduce this issue using qemu? |
Contributor
It doesn't make sense to try to reproduce this problem on QEMU: it's a different chip. ESP32-C3 has its own IRQs and memory protection unit. |
