Hi,
Regression. Builds fine with gcc-3.3:

/usr/lib/gcc-snapshot/bin/gcc --save-temps -c -ffast-math -fomit-frame-pointer
-D_REENTRANT -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I. -Inative -I..
-I../libmpdemux -I../loader -I/usr/include/libpng10 -I/usr/include/gtk-1.2
-I/usr/include/glib-1.2 -I/usr/lib/glib/include -D_GNU_SOURCE -o vf_hqdn3d.o
vf_hqdn3d.c

In function `PrecalcCoefs':

vf_hqdn3d.c:195: internal compiler error: tree check: expected integer_cst, have
real_cst in tree_int_cst_lt, at tree.c:3220
snapshot is from 20030815-1. Please let me know if I can provide any further
input.
Regards,

Confirmed. Here's something smaller: 
------------------------------ 
extern double log (double); 
 
void f(double x) 
{ 
    double g; 
    g = log(1.0 - x - 0.00001); 
} 
------------------------------- 
 
Compile with -ffast-math: 
tmp/g> ../build-gcc/gcc-install/bin/gcc -c -ffast-math vf_hqdn3d-snapshot.i 
vf_hqdn3d-snapshot.i: In function `f': 
 
vf_hqdn3d-snapshot.i:6: internal compiler error: tree check: expected integer_cst, have 
real_cst in tree_int_cst_lt, at tree.c:3220 
Please submit a full bug report,

Here are the dates from Phil's regression hunter: Search converges between 2003-08-11-trunk 
(#369) and 2003-08-12-trunk (#370).

Looks to be one of these patches, Roger could take a look?:
2003-08-11  Roger Sayle 

        * simplify-rtx.c (simplify_binary_operation): Replace calls to
        gen_rtx_NEG and gen_rtx_NOT with calls to simplify_gen_unary,
        and calls to gen_rtx_PLUS, gen_rtx_MULT, gen_rtx_LSHIFTRT,
        gen_rtx_ASHIFT and gen_rtx_AND with calls to simplify_gen_binary.

2003-08-11  Roger Sayle

        * expr.c (expand_expr): If an ABS_EXPR has a complex type, abort.
        * c-typeck.c (build_unary_op): COMPLEX_TYPE is not a valid
        typecode for an ABS_EXPR.

        * doc/c-tree.texi: Document ABS_EXPR.

2003-08-11  Roger Sayle

        * fold-const.c (fold): Optimize any associative floating point
        operator with -funsafe-math-optimizations, not just MULT_EXPR.
