Huh? I can't see where that error is coming from.. It's complaining about the use of jlimit with some kind of value, but LowLevelGraphicsPostScriptRenderer::restoreState doesn't call jlimit anywhere..?


Yep, I have so this as well when compiling with gcc with -O3, -Wextra. With -O0 there is no such message. And after commenting-out this part of code GCC complains in even more places than one.
