Andrew, do you know what an "indirect leak" is in LSan terminology?

An indirect leak means that according to its conservative analysis, some other leaked block contains a pointer to that leaked block. So in theory if you have a bunch of indirect leaks, and one direct leak, probably the root of the leak is the direct leak. Of course, in the presence of cycles, all bets are off.

I see.  And the lack of a direct leak suggests a cycle, right?

Yes.

Comment 10

[Ben Kelly [:bkelly, not reviewing]]

I don't think so.  Looking at the error reports it more matches bug 1232558.  Note, we haven't seen this error since I landed bug 1237158 which further suggests the connection.

Comment 11

[Ben Kelly [:bkelly, not reviewing]]

This has not triggered since bug 1237158 landed.  I'm going to close for now.
