What I would do now is to replace -O2 by -O1 and if this does not
anymore crahs, add these options:

          -fstrict-aliasing
          -fstrength-reduce
          -fthread-jumps
          -fcrossjumping
          -foptimize-sibling-calls
          -fcse-follow-jumps  -fcse-skip-blocks
          -fgcse  -fgcse-lm
          -fexpensive-optimizations
          -frerun-cse-after-loop  -frerun-loop-opt
          -fcaller-saves
          -fpeephole2
          -fschedule-insns  -fschedule-insns2
          -fsched-interblock  -fsched-spec
          -fregmove
          -fdelete-null-pointer-checks
          -freorder-blocks  -freorder-functions
          -falign-functions  -falign-jumps
          -falign-loops  -falign-labels
          -ftree-vrp
          -ftree-pre

one after another until it crashes.  A lot of work, though.
