Thanks for filing the bug and the extra info.

Without any prior known issues with turning on -g on fastdebug build
on Linux, except the size issue, I think I will see if it's got any

What I'd like to have is the ability to see nice stacktraces from gdb
without slowing down as much as the debug build.
