Declaring avg_slots_per_frame "volatile" (line 547 in lame.c) fixes it in
some cases. I was using the following test options, with fools.wav as my
source

-b 32 -f
-b 128 -f
-b 320 -f
-b 32 -h
-b 128 -h
-b 320 -h

Where before all were different, now only the 32kbps files are different.
With -b 32 -f, even the file sizes are different...

I'm using gcc 2.95.2 under WinNT, compiling with the following options

-O9 -fomit-frame-pointer -mpentiumpro -ffast-math     \
-funroll-loops -Wall -malign-double -mcpu=pentiumpro  \
-mfancy-math-387 -pipe

and the usual -DNDEBUG -D__NO_MATH_INLINES

BTW, can't check the -DABORTFP business, as this gcc doesn't support it (I
guess I don't have the right libraries).
