Subject: intern-soft C code: Empty *Summary* buffer, wrong argument type
Date: Tue, 18 Jun 2019 23:41:31 -0700

Hello! I tried the latest Emacs and broke my Gnus.

Tried with emacs -Q, and with a brand new user. Same results for nnimap and
nntp. When in the *Group* buffer, Gnus is able to retrieve news, but can't open
it. Upon pressing RET on a group, a *Summary* buffer is opened in the
background, but without any contents. Gnus commands in that *Summary* buffer
make errors, but the same one.

After digging around for a bit, it looks like intern-soft in the C code might be
causing the problem. Another issue I haven't been able to reproduce was
intern-soft returning NIL when an integer-or-marker-p was expected. In the
backtrace it is receiving wrong arguments.

After trying to open a group:
---------------------------------------------------------------------------- in
the *Messages* Buffer gnus-request-group: Wrong type argument: vectorp,
#s(hash-table size 9 test equal ...)  Gnus v5.13 GNU Emacs 27.0.50 (build 4,
