Would have been nice if you put the error message in the bug.

The difference between 4.1 and 4.2 come in the schedule1 pass.
4.1 does something while it looks like 4.2 does not.
-fno-schedule-insns on 4.1 fixes the ICE.

--- Comment #5 from dje at gcc dot gnu dot org  2006-02-18 16:47 ---
This appears to be related to -fpic.  The SYMBOL_REF is considered small data
and rs6000_legitimate_small_data_p() includes !flag_pic.  What is generating
this when -fpic?

Reload is creating the symbol_ref from the extenddftf2 splitter, which is
trying to load 0.0.  I think this is a case where we need to expand
legitimize_reload_address().  Darwin uses that to fix up these insns, but it
currently is disabled for SVR4 flag_pic.

#if TARGET_MACHO
   DEFAULT_ABI == ABI_DARWIN
   (flag_pic || MACHO_DYNAMIC_NO_PIC_P)
#else
   DEFAULT_ABI == ABI_V4
   !flag_pic
#endif
