Wennie, could you please redirect this to someone who can take a look at it? Thanks.

Comment 10

[Andrew McCreight [:mccr8]]

The most recent leaks are in /html/browsers/offline/introduction-4/

Anyways, I guess all of this Rust junk should be whitelisted at the top level so at least we can fix it in one place whenever the Rust people decide to rename their internal library functions or whatever and all of the whitelisting breaks.

Comment 11

[Andrew McCreight [:mccr8]]

I have a try run going to make sure I don't break anything horribly:

Comment 12

[Andrew McCreight [:mccr8]]

Attachment: Bug 1544115 - Consolidate whitelisting of Rust allocation functions for LSan WPT.

This whitelisting is not as mangled as the old one, so hopefully it
will be more resilient to changes in the Rust compiler. I moved them
to the top level white list, because like with the JS leaks we are
mostly focused on C++ leaks. Any interesting Rust leak is probably due
to a C++ leak.
