1021350 - Small leak under event_base_once

Status: RESOLVED WORKSFORME

(Core :: IPC, defect)

Description

[Andrew McCreight [:mccr8]]

LSAN detects a 152 byte leak while running Mochitest 4.  This could just be a one-time allocation we don't bother to free in non-debug builds.

Direct leak of 152 byte(s) in 1 object(s) allocated from:

This leak appears to be gone now. The suppression was removed in bug 1311584.
