1602645 - Add leak suppression for libfreetype.so

Status: RESOLVED FIXED

(Firefox Build System :: General, task, P2)

Description

[Andrew McCreight [:mccr8]]

egao is working on upgrading the OS we run ASan on from ubuntu1604 to ubuntu1804, and some new LSan leaks show up, in pretty much every suite.

==950==ERROR: LeakSanitizer: detected memory leaks
Indirect leak of 617120 byte(s) in 7600 object(s) allocated from:

Presumably this is a variation on one of the existing font leaks, so I'll add it to the suppression list.

Attachment: Bug 1602645 - Add leak suppression for libfreetype.so.

Changing the OS we run Linux ASan on from ubuntu1604 to ubuntu1804
causes 820800 bytes of leaks with libfreetype.so in the stack in
almost every test suite. Presumably this is just a variation on
existing leaks we get because we don't shut down fonts properly, so
just whitelist it.
