Chromium SIGTRAPs while creating new root window

[tiagovignatti]

open chrome and play around clicking with right-button to open/close menus in the address bar, wrench menu and in the Web content area. It's difficult to reproduce.

the command I've used to get the bt bellow was: gdb --args ./chrome --no-sandbox --single-process

I am unable to even start a debug session in single process mode, I hit 0x0000555556d32da9 in base::ThreadRestrictions::AssertIOAllowed () at ../../base/threading/thread_restrictions.cc:38 always even at start up. This is not related to root window creation but seems more of a thread issue.

[tiagovignatti]

true. and in fact it seems only related with --single-process due the content::InProcessUtilityThread running path.

[kalyankondapally]

hmm, I just noticed that gdb bt #(nos) are adding un-necessary noise to other bugs (referencing). Any good way to avoid this while including the bt ?

[kalyankondapally]

@tiagovignatti I don't see this anymore. I would propose to close this.

[tiagovignatti]

can't reproduce here anymore as well. I'm closing.
