This might be a duplicate of middle-end/5731.

>Description:
GCC 3.1 gets a segmentation violation compiling 301.apsi
and 168.wupwise from SPEC CPU2000 with "-O2 -ffast-math" on
ia64-unknown-linux-gnu. In both cases this occurs for a
divide of a complex*16 variable when expand_expr passes a
NULL op0 to expand_binop, which in turn passes it to
protect_from_queue.
This is a regression from GCC 3.0.4, for which these two
benchmark programs build and run with no problems using
these options.
>How-To-Repeat:
Compile with attached test case with "g77 -O2 -ffast-math".
>Fix:
Unknown.
