When I use cargo to compile my project which uses gl-rs, an ICE occurs. When I manually clone gl-rs and attempt to compile, I get the exact same error:

error: internal compiler error: unexpected panic
note: the compiler unexpectedly panicked. this is a bug.
note: we would appreciate a bug report: http://doc.rust-lang.org/complement-bugreport.html
note: run with RUST_BACKTRACE=1 for a backtrace
task 'rustc' panicked at 'quote! with interpolated token', >/home/dylan/repos/rust/src/libsyntax/ext/quote.rs:633

Could not compile gl_generator.

Here is the backtrace:

It's probably broken due to #17830

gl_generator doesn't use or define any macro, all it does is call quote!.

After some investigations, it comes from these two functions:

If I remove the doccomments from the inside of quote_item!, there's no ICE anymore.

EDIT: This commit removes the ICE: brendanzab/gl-rs@f14da1e

EDIT2: It's because of the vec![] macro.

Minimal test case:

vec![quote_item!(ecx, /** test */ fn hello() {})]]

This error originates in TokenTree's fn get_tt

Thanks!
