Find All References fails for variables on the last line of a file if there's no newline

[sean-mcmanus]

Do find all references on "abc1" in the code below:

int abc1 = 0;
int abc2 = abc1;

Bug: In the "C/C++ References" section it incorrectly gives

[Cannot confirm reference] test.cpp:1:20 int abc1 = 0;
int abc2 = abc1;

This seems like a corner case that no users would likely hit in normal code -- however, it's possible the root bug could be causing other issues so it might be worth investigating. It is worked around by adding a new line to the end of the file.
