I've hit the same issue with Vivaldi (a Chromium-based browser) for the first time after upgrading to the latest version recently.
It never happened before.

When it happened, I had ~32 tabs open and a few memory hog VMs running in the background.
The crashed tab was an item page on www.staples.com.

Version info:
Vivaldi       1.10.867.46 (Stable channel) (64-bit)

dmesg:
[679861.517865] mmap: vivaldi-bin (32524): VmData 2147684352 exceed data ulimit 2147483647. Update limits or use boot option ignore_rlimit_data.
[679876.537167] traps: vivaldi-bin[32524] trap int3 ip:55b38fbcf250 sp:7ffdab7a9190 error:0


My default VmData ulimit is unlimited:
$ grep 'data size' /proc/$$/limits
Max data size             unlimited            unlimited            bytes

But Chromium (Vivaldi in my case) sets it to 2147483647 for all renderer processes:
$ grep -h 'data size' $(printf "/proc/%s/limits\n" $(pidof vivaldi-bin)) | sort | uniq -c
     28 Max data size             2147483647           2147483647           bytes
      3 Max data size             unlimited            unlimited            bytes
