 Yes, please - this is in an area we have not touched (though it may already
 have been fixed, but I didn't spot any relevant changes on the 4.5 branch).

 Ideally a report would use a smaller demonstration program (the error is
 related to using a float value as integer, but I can't spot anything
 extraordinary in this regard in the mrtg code - it mostly uses long long
 and double).

 Btw, forgot to mention: compiling this single file with -O1 should work
 around the problem.

 For the record: this seems to be gcc bugzilla ticket #48830, fixed in
 upstream trunk, backport mostly impossible.
