[Swftools-common] error while compiling an sc file

[Francesco Potorti`]

Dear all,

I get these errors while compiling the appended sc file:

$ swfc viewer.sc
rfxswf: Warning: num_bits overflow in swf_SetRect
rfxswf: Warning: num_bits overflow in swf_SetRect
rfxswf: Warning: num_bits overflow in swf_SetRect
rfxswf: Warning: num_bits overflow in swf_SetRect
rfxswf: Error: matrix values too large
rfxswf: Error: matrix values too large
rfxswf: Error: matrix values too large
rfxswf: Error: matrix values too large
rfxswf: Warning: num_bits overflow in swf_SetRect
rfxswf: Warning: num_bits overflow in swf_SetRect

my compiler is

$ swfc --version
swfc - part of swftools 0.8.1

Any idea on where to start looking?  I compiled swftools myself starting
from the Debian sources, so I can easily recompile or change something
if needed.
