Package: golang-go
Version: 2:1.14~1
Severity: important
Dear Maintainer,
the current go binary crashes on mipsel when running non-trivial calls
(a trivial call would be like 'go version', which succeeds) with the message
'fatal error: gc_trigger underflow'. Here's an example from the mipsel
porterbox:

This also impacts mipsel builds of packages based on Go. I have tested
this on three of my own packages, e.g. slinkwatch (see
https://paste.debian.net/1146869/).
Best regards
