SIGSEGV when compiling on latest nightly #25

bacongobbler · 2020-10-09T17:52:19Z

This issue has reported upstream at rust-lang/rust#76930. Following the AVR Rust book, the program cannot compile due to a segmentation fault when compiling the core crate on the latest nightly build.

Looks like things work when I add -lc to the late-link-args parameter, partially reverting 76a28c4. That only works for the debug target, though. Adding --release still results in a segmentation fault.

Hmm... I cannot appear to reproduce this when I attempt to compile the program with the provided Dockerfile. Perhaps there's an issue with the linker being selected locally. I'll do some more research.

bacongobbler · 2020-10-09T22:57:27Z

Err, scratch that. It also appears to be an issue with Dockerfile.ci:

So it appears this is not just localized to my system, and it does appear to be related to an issue with the nightlies.

I had a similar error STATUS_ACCESS_VIOLATION at error: could not compile core with the release flag on Windows.

Looks like things work when I add -lc to the late-link-args parameter, partially reverting 76a28c4. That only works for the debug target, though. Adding --release still results in a segmentation fault.

Also had the same issue in my setup, this also seems to fix it 👍

erdeszt · 2020-10-19T20:41:39Z

I had the same issue and got it working with the -lc workaround and debug mode.
By changing the [profile.dev] config to:

opt-level = "s"
debug = false
debug-assertions = false
overflow-checks = false
lto = false
panic = "abort"

I got the output size down from ~700K to 8K which is acceptable to me for now.

I have the same problem. With or without erdezt's changes to [profile.dev]:

Slight modification of @erdeszt's workaround because I really just couldn't do without that release build (Cargo.toml in my case):

[profile.dev]
opt-level = "s"
debug-assertions = false

[profile.release]
opt-level = "s"

I've tested this modification on the dockerfile provided, it works on that and will also build for release.
Output sizes if anyone is interested:
elf: 11.8kb(debug), 6.6kb(release)
binary: 260 bytes (debug and release are the same size)

Before this, 'cargo build -Z build-std=core --target avr-atmega328p.json' would fail with linking errors to 'abort' and 'memcpy' symbols. After this patch, a debug mode executable can be successfully generated again.

Waits for seems to be fixed, I can't reprocuce the SIGSEGV or a simular update.

rust-lang/rust#76930 being solved allowed me to close this is issue.
(Feel free to report a fresh SIGSEGV when compiling on latest nightly)
