ICE When trying to build the rust opencl binding #20805
Description
While trying to update rust-opencl to build against the latest rust nightly, I ran in to the following:
/Users/cary/rust-opencl/src/hl.rs:456:29: 469:18 error: internal compiler error: aliasability violation with closure
/Users/cary/rust-opencl/src/hl.rs:456 write.write(|&: offset, p, len| {
/Users/cary/rust-opencl/src/hl.rs:457 let mut e: cl_event = ptr::null_mut();
/Users/cary/rust-opencl/src/hl.rs:458 let err = clEnqueueWriteBuffer(self.cqueue,
/Users/cary/rust-opencl/src/hl.rs:459 mem.id(),
/Users/cary/rust-opencl/src/hl.rs:460 CL_FALSE,
/Users/cary/rust-opencl/src/hl.rs:461 offset as libc::size_t,
...
note: the compiler unexpectedly panicked. this is a bug.
note: we would appreciate a bug report: http://doc.rust-lang.org/complement-bugreport.html
