🤖 New build scheduled with the buildbot fleet by @corona10 for commit 3f91a0b 🤖

If you want to schedule another build, you need to add the 🔨 test-with-buildbots label again.

I assume we can do this unconditionally on the mimalloc build no?

[corona10]

I assume we can do this unconditionally on the mimalloc build no?

Or we can use support.with_mimalloc(), but not a good use case for this script.

[pablogsal]

Nah is fine, just wanted to ensure that the header include is correct independently if we have mimalloc or not

[colesbury]

Thanks for fixing this.

Yeah, I think the include path is fine even if we are not compiling with mimalloc support.

[corona10]

We always include mimalloc headers through makefile.pre.in, so it's technically fine.
