#27670: Memleak on tor master 95fcad4088eba52e
------------------------------+-------------------------------------------
Reporter: dgoulet | Owner: (none)
Type: defect | Status: new
Priority: Medium | Milestone: Tor: 0.3.5.x-final
Component: Core Tor/Tor | Version:
Severity: Normal | Keywords: regression, memleak, 035-must
Actual Points: | Parent ID:
Points: | Reviewer:
Sponsor: |
------------------------------+-------------------------------------------
On latest master, normal client starts with a Ctrl+C. Notice the "Listener
on ???:0" which seems to me the end of a list we fail to recognize? And
then the memleak.
