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
