everytime I get this kind of template error message:

I get reaaaaaaally lost. I can't even visually parse where one error message starts and another ends. Are there any dev tools that can help me with this?

This gets particularly scary when I'm using boost libraries. :(

I think clang claims to produce more sensible error messages. — Kerrek SB, Jul 15 '11 at 15:11
normally, I look at the first line ("instanciated from...") and the last (the real error) - there should be enough information there to start figuring out what's going on... everything in the middle is noise IMHO.... — Nim, Jul 15 '11 at 15:20

STLFilt or use different compiler. Clang has supposedly better error messages (I cannot tell for sure, I didn't used it personally)
