Hi,
I'm getting invalid memory references (sic!) when building packages using bindgen.
What is interesting RUST_BACKTRACE doesn't show any backtrace.
I read cargo env variables and bindgen option for some debbuging but there is none.
Here is cargo build output
spock:~/kea-module$ RUST_BACKTRACE=1 cargo build
Compiling kea-module v0.1.0 (file:///home/spock/kea-module)
error: failed to run custom build command for `kea-module v0.1.0 (file:///home/spock/kea-module)`
process didn't exit successfully: `/home/spock/kea-module/target/debug/build/kea-module-50631c877f7517a1/build-script-build` (signal: 11, SIGSEGV: invalid memory reference)

Is there other methods to debug cargo so I can see what is wrong ?
Those files are not build scripts, those are elf binaries (probably generated by bindgen).
Just to be clear here, a "build script" in a cargo project is a Rust binary that cargo compiles into a native binary and runs to do some work at build-time. Often these do things like generate Rust code (sometimes using bindgen), build C++ projects, or find native libraries to link against.
bindgen uses libclang, so it's possible for it to cause crashes there.
