This error has been haunting us recently, firstly on Greg's machine when compiling the compiler using the new SBT build, and more recently during PR validation in scala#4316. This commit will output an error like: symbol value c#16812 does not exist in Macro.impl, which contains locals value a#16810, value b#16811 I've included symbol IDs in the hope that they will prove useful. It seems that synthetic identifiers generated by the pattern matcher are often seen in the vicinity of this bug.

It sure would be nice if that didn't look like a one. It's too bad I sound so ungrateful when I say that. I bet we could make good use of the Turkish undotted i.

I agree one letter identifier is not ideal but it's been like that before.

We have seen an intermittent crasher in the backend for the last month or so. In scala#4397, I added a diagnostic to show the actual locals in scope in the method. This commit further expands the diagnistic to show the method's tree.
