and if you try on windows intel c++ 5.0.1 next:
  CFLAGS    = -O3 -G6 -Qaxi -Qxi -Gr -Qprof_genx

then delete object files and try again:
 CFLAGS    = -O3 -G6 -Qaxi -Qxi -Gr -Qprof_use

How's its speed then?

this should speed you up huge, as you're not using G6 above nor Qaxi nor GR.

ipo was producing buggy code for me.

Is the 6.0 compile producing same output like 5.01?

Minority viewpoint in this world, nevertheless more common in this forum :)
