Any way to bisect using ASan builds with this tool?

[svn-dys]

Trying to bisect a Chromium issue, but would like to use ASan builds instead.

Try adding:

--asan

to your command line. You can also run:

chrome_bisect --help

to see all options.

Thank you for helping!

I see this error:

chrome_bisect.exe -a win -g 1078752 -b 1078011 --asan -- --enable-features=Portals

The bisect range is from 12/1 (1078011 ) - 12/2 (1078752)... which seems reasonable. I cannot bisect past 852410? Am I doing something wrong?

Hi,

Anyway to fix this issue? I am trying to bisect a UAF that seems to only reproduce on ASan builds. I cannot bisect builds past rev 852410 with the --asan switch. :(

It seems to be an issue with the underlying script, not much I can do there right now.
