The tests crash with an OOM in some v8 code. There are two v8 rolls in the regression range and I didn't find other suspicious commits.
The failures started in this build https://build.chromium.org/p/chromium.gpu.fyi/builders/Linux%20Release%20%28Intel%20HD%20530%29/builds/617
The v8 rolls:
https://chromium.googlesource.com/v8/v8/+log/309a9310..942ddf2c

Tentatively assigning to bmeurer@, to my untrained eyes the "[turbofan] Always inline small functions directly." commit looks like it could be causing the issue: this dEQP test contains many many small functions.
