Description :
calling "frama-c -val 116.cpp" eventually leads to a user error:
[value] Done for function foo::Ctor 116.cpp:10:[value] user error: Function argument __fc_tmp_0 has unknown size. Aborting [kernel] Plug-in value aborted: invalid user input.
The error message disappears if either
- a variable (e.g. "int v;" after line 3) is declared inside class "foo",
- the call "f.cat(f);" is omitted in line 10, or
- the argument type of "cat" is changed to "int" in line 5 and "f" is replaced by "0" in line 10.
Apparently, the "f" in line 10 somehow causes an empty struct to be generated, which is not properly accepted.
