Has a pattern similar to  issue 727269  (started failing at the same time), could be related?

These TabModelTest.* tests have started failing quite consistently:

test                                       build                     status
TestProfileHandling (CRASHED)               2850  FFFF~F~F~FFFFFF-~~--~---~
TestProfileHandlingOffTheRecord (CRASHED)   2850  FFFF~F~F~FFFFFF-~~--~---~

Build with first failure is:

With a short CL range:

Maybe also related to?
