I found that, with all versions since (and including) chromium
63.0.3239.84-1, Chromium would crash (SIGSEGV) shortly after startup or
immediately at startup.
Initially, I found that disabling the uMatrix extension I have installed
(from the Chrome Web Store) would avoid the crashes. That wasn't a
suitable work-around, so I've been held at version 63.0.3239.40-1.

I found these information interesting, relating to this bug:
1) a bug report for ArchLinux re: Media Router Component, with a comment
noting that the "load Media Router Component extension" flag may cause
Chromium to crash:
https://bugs.archlinux.org/task/51832#comment154874
2) Debian ships Chromium with a "default-flag" to disable the media router:
$ grep -n media /etc/chromium.d/default-flags
15:# Disable the builtin media router (bug #833477)
16:export CHROMIUM_FLAGS="$CHROMIUM_FLAGS --media-router=0"
3) a bug report for Debian, much like the ArchLinux one above:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=833477
