runtime: frequent failures with `sys: trap` on plan9/386 and plan9/amd64 #50137

bcmills · 2021-12-13T20:20:13Z

post <- builder ~ `^plan9-.*` && `(suicide:|fatal error:|signal) sys: trap: (fault|general protection violation)`

# internal/poll [io.test]

FAIL	io [build failed]

These occur in lots of different binaries, and have occurred (but much less frequently) on plan9-arm.
@0intro, could you investigate? This appears to be one of the more frequent failure modes on the plan9-386-0intro builder, and since it appears to affect all Go binaries we cannot easily work around it by skipping one or more tests.

greplogs --dashboard -md -l -e 'suicide: sys: trap: fault'

The text was updated successfully, but these errors were encountered:

bcmills · 2022-01-06T16:04:46Z

This also appears to manifest as fatal error: fault:

greplogs --dashboard -md -l -e 'fatal error: fault\n\[signal sys: trap: fault'

bcmills · 2022-04-07T17:20:18Z

This is still a frequent failure mode on the plan9-386-0intro builder:

greplogs --dashboard -md -l -e 'fatal error: fault\n\[signal sys: trap: fault' --since=2022-01-07
