Subject: Avoid assertion violation at startup in pdumped Emacs
X-Git-Tag: emacs-28.0.90~7691
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=ced7852046469b8248718d5c95c64c0cd4ddf417;p=emacs.git

Avoid assertion violation at startup in pdumped Emacs

* src/buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Remove the
assertion that ensured all buffers in pdumped Emacs have non-NULL
pointer to buffer text.  That was false when Emacs was pdumped
with killed buffer(s) in the all_buffers linked list.  See
https://lists.gnu.org/archive/html/emacs-devel/2020-03/msg00800.html
for more details.
