user bug: values multiplied by zero returnin extreme results

[CTZn]

edit: my mistake, there is no such Indigo bug. The shared code was duplicated into the parameter shader on which I worked quite some time until conflicts became obvious. I even halted my PC in order to repeat the said bug. I understood my mistake this Saturday night...

in fact, whole terms get ignored in definitions intermediary to eval(), wich in turn responds normally if modified.

The shader is displacement. Values are multiplied by zero in several instances yet yield a differentiated output.
