OK, some of the optimisations in -O2 are the culprits... -O1 works...

choose freely:

-O2 turns on all optimization flags specified by -O.  It also turns on the 
following optimization flags: -fforce-mem -foptimize-sibling-calls 
-fstrength-reduce -fcse-follow-jumps  -fcse-skip-blocks 
-frerun-cse-after-loop  -frerun-loop-opt -fgcse  -fgcse-lm -fgcse-sm  
-fgcse-las -fdelete-null-pointer-checks -fexpensive-optimizations 
-fregmove -fschedule-insns  -fschedule-insns2 -fsched-interblock  
-fsched-spec -fcaller-saves -fpeephole2 -freorder-blocks 
-freorder-functions -fstrict-aliasing -funit-at-a-time -falign-functions  
-falign-jumps -falign-loops -falign-labels -fcrossjumping
