Subject: cmd/gc: remove bad check for BADWIDTH
X-Git-Tag: go1.1rc2~1675
X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=0d22573f6e053ae12c09d65a8b7c4d5b604317fb;p=gostls13.git

cmd/gc: remove bad check for BADWIDTH

This check for BADWIDTH might happen while in defercheckwidth, making it raise errors for non-erroneous situations.

Fixes #4495.
