this is my function
world is a b2world image is a sprite
function createBodyFromImage(world, image, bodyDef, ...)
local fd = {}
local dDef = {}
if bodyDef then
dDef = bodyDef
end
if dDef.type == nil then dDef.type = b2.DYNAMIC_BODY end
if dDef.position == nil then dDef.position = {x = image:getX(), y = image:getY()} end
--print(dDef.position.x)
local body = world:createBody(dDef)
if arg.n > 0 then
fd = arg[1]
end
if fd.shap == nil then
print(fd.shap )
local shape = b2.PolygonShape.new()
shape:setAsBox(image:getWidth()/2, image:getHeight()/2)
fd.shap = shap
--[[
local shape = b2.PolygonShape.new()
shape:setAsBox(40, 40)
body:createFixture{shape = shape, density = 1, restitution = 0.2, friction = 0.3}
]]
end
if fd.density == nil then fd.density = 1 end
if fd.restitution == nil then fd.restitution = 0.2 end
if fd.friction == nil then fd.friction = 0.3 end
body:createFixture(fd) -----this line make the player crashed
image.body = body
b2Sprites[#b2Sprites + 1] = image
end

Comments
I made a type mistake
fd.shape = shape is OK
However this should not crash the player
