You are probably looking for a change made after 538041 (known good), but no later than 538042 (first known bad).

CHANGELOG URL:

The script might not always return single CL as suspect as some perf builds might get missing due to failure.

https://chromium.googlesource.com/chromium/src/+log/b82cc83c724a875f27ff7986cb3037e9231e8999..e24c90e284ccaae925132cc0271d9179b5560ec3

Suspect : https://chromium.googlesource.com/chromium/src/+/e24c90e284ccaae925132cc0271d9179b5560ec3

From the CL above, assigning the issue to the concern owner 

@fsamuel- Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Thanks!
