Cadical 1.6.0 MS VC++ breaks for --shrink > 0

[Axel Kemper]

I compiled Cadical 1.6.0 in three flavors:
with MS VC++ 2022, with MSYS2 MinGW 64 and with Windows WSL2 Ubuntu g++ 11.3.0.

The MS VC++ binary stops with an assertion violation
(cf. observation by deiruch)

line 226 of shrink.cpp: assert (v.reason);

As a workaround, I can use --shrink=0 as commandline parameter.

The other two binaries don't exhibit this problem.

Oh well, I guess this is a Microsoft compiler issue then (the other two Windows builds
use 'gcc' I assume). We are busy continuing to merge our SAT papers code (LRAT is next)
then we will have a look at this.

We are still short of being able to test MS VC++ compilation, so will keep this open.
