Description
rustc fails to build my crate in release mode with debugging symbols.
The crate is located here: https://github.com/ethcore/parity/tree/master/ethcore
It is hard to pinpoint the exact piece of code responsible since the error message gives no such indication.
Running cargo rustc --release -- -g fails with the following message:
Assertion failed: (std::all_of(Expr.begin(), Expr.end(), [](const DIExpression *E) { return E && E->isBitPiece(); }) && "conflicting locations for variable"), function addMMIEntry, file /Users/rustbuild/src/rust-buildbot/slave/nightly-dist-rustc-mac/build/src/llvm/lib/CodeGen/AsmPrinter/DwarfDebug.h, line 137.
Stack trace:
Program received signal SIGABRT, Aborted.
