[BUG] Rust compiler optimizations crashes arrayfire #299
Description
Description
Similar to bug #73 , rust compiler optimizations create instability the program and will result in a crash
Setting compiler optimizations to the highest level
[profile.release]
opt-level = 3
and building a rust program in release mode
cargo build --release
crashes my program and GPU drivers.
Hilariously, my screen turned blank and I didn't get to see the error message.

Can you also please update the description with details like OS, ArrayFire(installed library) version, ArrayFire crate version, Backend being used, GPU driver version.
To get some clarification, just compiling
cargo build --releaseis causing the crash or running the program built withopt-level=3is causing the crash ?BA8F0D39 commentedon Oct 5, 2021
It seems jemalloc isn't compatible with arrayfire
#[global_allocator]
static ALLOC: jemallocator::Jemalloc = jemallocator::Jemalloc;

@BA8F0D39 I assume, you are referring to the CPU backend because it should not be a problem for CUDA/OpenCL except in few minor set of APIs where host side allocations take place for strings etc.
I haven't used jemalloc, so I would have to try it and check where the incompatibility stems from. Is it the upstream lib or something in rust crate. I suspect it could be upstream lib but cannot be certain about it yet.

Sorry, couldn't get back to this. Will try this weekend.

can you please tell how do I reproduce this on my end ? perhaps your stand alone code from your project that uses jemalloc.
Just the opt-level(3) and --release flag definitely aren't the problem as you have already pointed that out and I was able to run examples with those settings. Graphics examples are not working on my current system, but I don't think these are related.

Closing due to inactivity @BA8F0D39 feel free to re-open if you still have the issue reported or more info to share.
