--- Comment #11 from seberg <sebastian-gcc at sipsolutions dot net> --- Does that mean that fixing the `#line` directives (or inserting additional ones) should be able to fix the issue? (Or work around it, if you consider it a bug.) I tried to figure out where the `#line` directives currently causes this situation, and add new ones in some places in the templater. But I don't really see where it goes wrong. That is, unless `#if 0` causes the directives within the block to be ignored?
