I have this problem all the time with skipped template instantiations
in error messages in GCC. Sometimes I just can't know which code
causes the problem because its instantiation isn't listed in the error
message. This is *very annoying* and I just surrender and try with
MSVC to find the root cause of the problem. It is not always the
leaf, nor is always the first instantation as well.
