Just FYI, I'm also seeing this. On an up to date Debian testing, same version (62.0.3202.89-1).
I can reproduce it on a fresh profile, and also incognito is affected, so it's completely unusable. -g makes no difference in my case (also crashes). If I "rm -r ~/.config/chromium" and then run "chromium --incognito", it opens and runs for about 4m of light use (browsing simple websites in two tabs, for example) before crashing. Subsequent runs crash right after launching. This seems to be 100% reproducible here. Traceback obtained with gdb: Thread 1 "chromium" received signal SIGABRT, Aborted. __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:51 51 ../sysdeps/unix/sysv/linux/raise.c: No such file or directory.
