Can you provide me with the stacktrace for 1.4-SNAPSHOT? The entire implementation has changed, I need to know the correct line numbers.

@pyricau here you go:

@kylefowler got this one too. Could you confirm it happens on Marshmallow only?

kylefowler · 2015-09-10T20:41:04Z

yeah, only seeing it on M

jacobmattsson · 2015-10-21T10:29:35Z

@pyricau Any progress on this (six weeks since last activity)? LeakCanary seems unusable on Marshmallow (even with 1.4-SNAPSHOT). Is there any workaround? Saw your talk on Droidcon NYC and thought I'd give it a try ... Thanks!
