Wrong assembly code is here:

   0x000030f4 <run_me_+396>:    fsub,sgl fr17,fr17,fr22
   0x000030f8 <run_me_+400>:    fabs,sgl fr22,fr22
   0x000030fc <run_me_+404>:    fcmp,sgl,!< fr13R,fr22
   0x00003100 <run_me_+408>:    ftest
   0x00003104 <run_me_+412>:    b,l,n 0x37f0 <run_me_+2184>,r0

This is with a slightly reduced testcase.  Bug disappears when I tried to
reduce run_me.
