Versions, syntaxes ("z3 crashed and produced no output")

Hi all,

it looks that current vcc crashes on old syntax (or perhaps invalid includes):


$ cat test.c 
#include "vcc.h"
void test() {};
$ vcc test.c 
Verification of test caused an exception "z3 crashed and produced no output".
Exiting with 3 (1 error(s).)~$ vcc /version
$ vcc /version
Microsoft Research Vcc Version 2.1.31105.0
Microsoft Research Boogie Version 2.1.21027.0
Microsoft Research Z3 Version

What is the recommended last version to use for the old (2009-mid 2010) syntax?

The old syntax is still fully supported and not the cause of your problem (as z3 does not even report its version number). Why z3 does not run, I don't know, but try running it directly and see if it reports some error.

Hi Stephan, yes (having done a reinstall today), z3 now does report a valid version number and everything looks perfect :-)

(Addendum: having done some forensics (the reinstall was on another machine so I still had to fix the original one), it was a vcomp100.dll that hat been missing from "c:\windows\system32" - this vcomp100.dll that recent versions of z3 apparently depend on can be found e.g. in the Microsoft Visual C++ 2010 Redistributable Package.)
