When I use the resulting rustc and run my crashfinder which runs
RUST_BACKTRACE=full "build/x86_64-unknown-linux-gnu/stage2/bin/rustc" "./src/librustc_ast_lowering/pat.rs" "-Zmir-opt-level=3" "--emit" "mir" "-Zsave-analysis" "-o" "/dev/null" "-Zdump-mir-dir=/dev/null"
I get the following crash:

stack backtrace:

However I have not managed to reproduce this by executing the command in the command line for some reason :/

rustc is @ 75b0a68
