Description Rodrigo Moya 2016-03-14 18:52:21 UTC
Some classes (OutOfMemoryException allocated at startup by the runtime) have no associated stack trace, so when drilling down to them, a list with an empty method is displayed as the only data in the list, which is confusing, so we should probably avoid drilling down in those cases.

@Rodrigo, Could you please add more Steps or Screencast to reproduce this issue, so that I can confirm this issue at our end.
Comment 2 Rodrigo Moya 2016-07-04 09:55:10 UTC

1. Group allocations summary by method (for System.String for instance)
2. Sort by caller and see if there is a row with an empty value for the 'Caller' column
3. Double click on it to see the allocations for that group

Before the allocations summary+list merge, this was just displaying a list of allocations without a stacktrace, but now, it even crashes

I have checked this issue with the help of steps provided in comment 2 but I am not getting any empty value for the caller column with latest build i.e. 0.34.0.

And I am able to reproduce this issue with previous profiler build i.e 32.99.124.

@asim @rodrigo can we resolve it as NOT_REPRODUCIBLE/FIXED?
Comment 5 Rodrigo Moya 2016-08-08 11:14:48 UTC
Yes, we no longer drill down to stacktraces anymore, so this shouldn't happen anymore, so closing
