0002039: WP-Plugin crashes due to an internal error when terms of sets during union have different types
In case type of terms of tset1 and tset2 is different, then assigns \union(tset1, tset2) causes WP to crash.

In the example in attached file, first set has terms of type int, and other set set has terms of type double. union is throwing following error:

failure: c-object of logic type (ℝ)
 
When attached file is called with the following command-line:

frama-c -wp-fct copy -wp-print -wp-out temp -continue-annot-error array_assigns.c

Frama-C produces below output:

[kernel] preprocessing with "gcc -C -E -I. EditorTest/src/FVal_Infer/array_assigns.c"
[wp] Running WP plugin...
[wp] Collecting axiomatic usage
[wp] warning: Missing RTE guards
