Subject: Re: bug#36019: 27.0.50; Segfault in color_distance in emacs --batch

From: Vitalie Spinu <[email-masked]>

I have bisected it to:

yes: 5d8b0fadee * | Add terminal hook query_frame_background_color
err: 41e20ee4bc * | Add terminal hook defined_color_hook
err: a411517faf * | Rename generic x_* identifiers
err: da9541dd10 * | Add prefixes to some window system-dependent procedures
 no: ff4e31fa32 * |  Rename generic x_* procedures in xdisp.c

The commits marked with err: don't build. So should be one of the top 4 commits.
