Description
I'm using an MSYS2 shell on Windows 7 64bit. I tested this on 1.0, the 1.1 beta, and the latest nightly (rustc 1.1.0-nightly (21f278a68 2015-04-23) (built 2015-04-24)).
When I try to compile maurizi/rsnotify@68db23b using cargo build --verbose I get the following error:
$ cargo build --verbose
Fresh libc v0.1.8
Fresh walker v1.0.0
Fresh gcc v0.3.8
Fresh bitflags v0.2.1
Fresh log v0.3.1

If I comment out the body of this function it will successfully compile maurizi/rsnotify@fc28778. Though it seems to be the if let statement causing the issue: if I leave out the unsafe body in the if let block, I still get an ICE
