In the minimal example (to be attached), g++ crashes with a "please submit bug
report" message.
The goal of the original code was to provide a generic multi-label connected
component algorithm. Therefore, I wished to output a label along with each
Component of the same type as the input data 2d array----decltype(data[0][0]).
However, when I added a lambda expression as part of operating on something
related to this type, g++ began crashing during compile.
I realize that in some cases decltype(data[0][0]) may have a reference type so
this code may be invalid; however, the compiler still should not crash, but
simply report an error.
