Maybe try an older cvs build or check-out the sources from a few days
or weeks ago.

wd: How do I get these older sources?

using a clean build from 01.November.06 (11.01.06) the instabilities do not yet occur.

core=dynamic does not cause any problems.

pre-compiled binaries: http://builds.tharos-online.de/

Should be the -D parameter of cvs, something like "-D 2007-01-20".
But the prebuilds might be easier.

I'm pretty sure kruwi is using Linux 😀

yes I am ... .

SMC code? Try just before jan 18...there was a big dynamic core update on the 18th.

> there was a big dynamic core update

Dunno why the full core should be broken then. But maybe you
can determine the rough date when it's broken.

I actually find it difficult to access the older cvs-sources. Maybe someone could upload a linux-build (a clean one) or the sources (even better) from ~ 1-2 weeks ago?

cvs seems just fine, try something like
cvs -d:pserver:anonymous@dosbox.cvs.sourceforge.net:/cvsroot/dosbox co -D 2007-01-17 -P dosbox

OK. I have managed to access the cvs-repository and have compiled and installed the dosbox-cvs from 2007-1-17.

Everything works normally with this version of dosbox-cvs. Core=dynamic does not lead to any problems. Windows 3.1 runs pretty stable, as it has done ever before.

So, I think I am finally able to specify the problem: The "bug" only appears in cvs-versions 2007-1-18 and later.

I think I can by now almost definitely rule out that the problem is caused by a corrupted win3x installation. For me, this looks plainly like a post 2007-1-18 bug.

yep, sounds like your system does not like the SMC of dynamic core. What linux system are you using and is it 32bit or 64bit and what compiler (gcc 3.x or 4.x). That all means nothing to me of course, but maybe the devs can do something with this information 😀

I'm using the 32 bit version of opensuse 10.2 .

My system is a centrino laptop (M 740, 1.6 GHZ) with 1 GB RAM.

The gcc version is 4.1.3-29.i586

P.S.: What is SMC?

You could try uncommenting the #define X86_INLINED_MEMACCESS
at the top of src/cpu/core_dyn_x86/decoder.h and see if it works then.

Does it happen to anybody else? I've tried several versions and it is
as stable as before.

Ok, after I uncommented this line I tried to compile the sources and got the following error messages:

Seems stable here (with SMC changes), though I only run some win3x MIDI apps for testing.

Sorry, i meant out-comment, should look like this.
