crash on macOS 10.15 (Catalina) beta 8 19A558d

cargo run --release will crash when using jemallocator. I tried on two machines running macOS 10.15 beta, both will produce the same result.

#[global_allocator]
static ALLOC: jemallocator::Jemalloc = jemallocator::Jemalloc;

fn main() {
    println!("Hello, world!");
}

got output:

fish: 'cargo run --release' terminated by signal SIGSEGV (Address boundary error)

backtrace is:

maybe it's a bug of macOS, I found a similar issue https://bugzilla.mozilla.org/show_bug.cgi?id=1570451#c41

Could you report this as well to jemalloc upstream and link that bug report here? Thanks.

[velvia]

I'm getting the same thing on OSX 10.14.6 as well.

[saagarjha]

Since none of the relevant code is around in a recent version of jemalloc, perhaps someone who can reproduce the issue should try bumping the version shipped with jemallocator?

[virtualritz]

I am seeing a segfault on Catalina 10.15.4 when I swap the default allocator out for jemallocator in one of my projects. It only happens though when that project calls into a *-sys crate that binds to a third party DSO.

[saagarjha]

Hmm, that is strange…would you mind sharing a crash log? I was seeing this in jemalloc's constructor, and I can't reproduce it in your project :(

[virtualritz]

I never get a crash log.

Steps to repo (just tried):

# Assuming you are on macOS,
# cloned https://github.com/virtualritz/rust-diffusion-limited-aggregation.git
# and downloaded & installed 3Delight (I'm using 2.0.7 since today).

git checkout b3942167a0aa1817e4d44bb1203c606083a3480c

Actually, I did get one; in Console:
