simple equation system -- crashing M5?

Quite frankly, I'm stymied ... the equation system below manages to fry
Mathematica 5 on my system.
It starts of (more or less) fine, using about 2.2GB ram, before---rather
suddenly--Mathematica vanishes from the screen ... no error message, no
Kernel shutdown, no output, no save ... ziltsch

Has anyone had such an experience?? Any ideas??

Here's the equation system:

Solve[{M0 == (1 - f1 - f2 - f3 - f4 - f5 - f6 - f7 - f8 - f9 - f10 - f11 -
f12 - f13 - f14 - f15 - f16)*m0,

M1 == f1*m0 + (1 - f1 - f2 - f3 - f4 - f5 - f6 - f7 - f8 - f9 - f10 - f11 -
f12 - f13 - f14 - f15 - f16)*m1,

M2 == f1*m1 + f2*m0 + (1 - f1 - f2 - f3 - f4 - f5 - f6 - f7 - f8 - f9 -
f10 - f11 - f12 - f13 - f14 - f15 - f16)*m2,

M4 == f1*m3 + f2*m2 + f3*m1 + f4*m0,

M5 == f2*m3 + f3*m2 + f4*m1 + f5*m0,

M6== f3*m3 + f4*m2 + f5*m1 + f6*m0,

M7== f4*m3 + f5*m2 + f6*m1+ f7*m0,

M8== f5*m3 + f6*m2 + f7*m1+ f8*m0,

M9== f6*m3 + f7*m2 + f8*m1+ f9*m0,

M10== f7*m3 + f8*m2 + f9*m1+ f10*m0,

M11 == f8*m3 + f9*m2 + f10*m1 + f11*m0,

M12 == f9*m3 + f10*m2 + f11*m1 + f12*m0,

M13== f10*m3 + f11*m2 + f12*m1 + f13*m0,

M14== f11*m3 + f12*m2 + f13*m1+ f14*m0,

M15== f12*m3 + f13*m2 + f14*m1+ f15*m0,

M16== f13*m3 + f14*m2 + f15*m1+ f16*m0},

{f1, f2, f3, f4, f5, f6, f7, f8, f9, f10, f11, f12, f13, f14, f15, f16}]
