Bug #913271 [llvm-7] segfault - broken rust compiling
Bug #913500 [llvm-7] cargo FTBFS: rustc segfaults
Set Bug forwarded-to-address to 'https://bugs.llvm.org/show_bug.cgi?id=39427'.
There's an ABI incompatibility between LLVM compiled with GCC and Clang:
https://bugs.llvm.org/show_bug.cgi?id=39427
So if you have a Clang-built libLLVM.so, and rustc's src/rustllvm is
built with GCC, then I think you may be hitting this problem.

The segfault is triggered by the presence of debuginfo=N where N != 0. You can
avoid it by setting RUSTFLAGS or running "cargo rustc -- -C debuginfo=0"
instead of "cargo build".
Together with the workaround for #913414, this means a temporary workaround for
users could be to set RUSTFLAGS="-C

I can provide some reproduction steps, if that's helpful.
1. Install rustc and cargo.
2. git clone https://github.com/rust-lang-nursery/rust-clippy.git
3. cd rust-clippy
4. git checkout

I've just updated my Sid install and found that building Rust crates
with Cargo now fails with a seg fault.
Initially I fired a bug report at cargo to kick things off, but I've
now discovered that it relates to the llvm-7 update, as
11 matches
