cargo build : failed to "SIGSEGV: invalid memory reference"

[magj2006]

Problem
I made new project A by using cargo new A， and then cd into A, there was an error when execute cargo build as shown below:

$ cargo build

[alexcrichton]

Hm this definitely looks quite bad! This looks like both Cargo and/or rustc may be segfaulting. The backtrace you've got here though is from SIGUSR1 which is expected (in a rustc process). Would it be possible to get a backtrace from the actual segfault?

[alexcrichton]

(it may be best to enable core dumps and then rerun rustc and debug the core dump)

[dwijnand]

Closing due to incomplete information.

[ConnorGray]

@dwijnand Would it be possible to reopen this issue? I'm encountering this error consistently when attempting to do a --release build.

I've observed this on nightlies goes back to at least nightly-2018-12-26, but also the most recent nightly-2019-03-1. I'm using macOS 10.12.6.

I'd be happy to provide more information, though currently as @alexcrichton mentions, I'm only seeing the backtrace for the SIGUSR1 signal, not the original SIGSEGV.

How might I use lldb to get the backtrace for the SIGSEGV signal? At the moment I'm doing $ lldb cargo -- build --release.

[dwijnand]

Sure! Have you tried enabling core dumps?

[ConnorGray]

@dwijnand I was able to generate a core dump for the crash. Viewing the backtrace of the core dump in LLDB doesn't seem to include any other information than what I saw when I used lldb to debug the running process.

Is there some something specific I might look for within the core dump which would help narrow this down?

Edit:

I realized the problem was likely in a different thread. Of the 6 threads recorded in the core dump, only one wasn't within libsystem_kernel.dylib. It's backtrace is here:

https://gist.github.com/ConnorGray/681e22756b147a4e8afa1b90447d6d4b

[ConnorGray]

This seems to be related to LTO. I noticed that setting lto = false in Cargo.toml tended to reduce the likelihood that rustc would crash (though it didn't eliminate the crash completely).

[gpit2286]

I'm seeing this too. Some information (OSX 10.14.3)

I'm getting this on raspi when doing --release builds

• happens on raspi3 with 512M RAM but also on raspi4 with 4G RAM
• dev builds are fine
• reducing number of jobs doesn't help
• happens on regular project but also on cargo new hello
• lto: false doesn't help

cargo --version
cargo 1.38.0 (23ef9a4ef 2019-08-20)

rustc --version
rustc 1.38.0 (625451e37 2019-09-23)

I can provide any other info if you tell me how to get it :)
