What did you see instead?

go install golang.org/x/text/cmd/[email protected]

The same error happens when calling gotext rewrite.

Change https://go.dev/cl/529255 mentions this issue: cmd/gotext: fix segfault in extract & rewrite commands

Looks like a duplicate of #60555

Looks like a duplicate of #60555

I don't think they are the same, this issue is related with parsing the command line flags of gotext.

[mauri870]

This is still present in gotext as v0.15.0.
