<br>
We’ve been using bmalloc on Mac and iOS for some time now, and it is fast and stable.<br>
<br>
Is there a Linux maintainer who would like to take on enabling bmalloc on Linux? The implementation is Unix-y, so it should “just work”. I can advise on this project, but I don’t have a Linux build & test environment.<br>
<br>
I plan to remove TCMalloc soon.<br>
