Reassigning these reports to the 'source' package. Could you do some
statistics with -fmem-report comparing 3.2.3 and 3.3? Preprocessed
source would be nice, although the increased memory usage is known
upstream.

Could you try to reduce the optimization settings, i.e. is
-funroll-loops really needed for this file and does it result in
better performance? They are not Debian standard
anyway. -fexpensive-optimizations isn't needed, as it's turned on at
-O2. -O6 does not make any sense, -O3 is the "max".
