This bug has been there since the first checkin. I'm curious, did it actually cause a problem or did you just see it while reading?

The patch is right. Most of the other uses elide storing the position the non-unique elements got moved to, and does "indexes.erase(std::unique...)" but either form is fine by me.

clang drew my attention to it:

Symtab.cpp:620:5: warning: ignoring return value of function declared with 'warn_unused_result' attribute [-Wunused-result]

std::unique(indexes.begin(), indexes.end());
