This code from insert.c lines about 1044-1050 is clearly involved.
The complaint is that the auxchfree is freeing memory already freed in
the call to csound->Free earlier.  No idea about subinstr but it looks
as if it s the culprit

          if (ip->auxchp != NULL)
            auxchfree(csound, ip);
          free_instr_var_memory(csound, ip);
          if ((nxtip = ip->nxtinstance) != NULL)
            nxtip->prvinstance = prvip;
          *prvnxtloc = nxtip;
          csound->Free(csound, (char *)ip);
        }

Yes, I found that too with the VS debugger. But I have absolutely no idea what code could have made that memory be freed before the auxchfree function...

That code seems OK, wondering how Free got called then.

Well it doesn’t crash here, but that’s not really saying anything. However,  running with -v I get reports from auxchfree, but none
concerning instr 2 (meaning it’s not being called):

This code from insert.c lines about 1044-1050 is clearly involved.
The complaint is that the auxchfree is freeing memory already freed in
the call to csound->Free earlier.  No idea about subinstr but it looks
as if it s the culprit

        if (ip->auxchp != NULL)
          auxchfree(csound, ip);
        free_instr_var_memory(csound, ip);
        if ((nxtip = ip->nxtinstance) != NULL)
          nxtip->prvinstance = prvip;
        *prvnxtloc = nxtip;
        csound->Free(csound, (char *)ip);

I noticed that to make it crash there should be at least 3 score events for Instr 1. With 1 or 2 'i1' events it doesn't crash. With this score:

<CsScore>
i1 0   1 262 0.25
i1 0.1 1 292 0.25
i1 0.2 1 342 0.25
</CsScore>

The output with -v is this:

This code from insert.c lines about 1044-1050 is clearly involved.
The complaint is that the auxchfree is freeing memory already freed in
the call to csound->Free earlier.  No idea about subinstr but it looks
as if it s the culprit

        if (ip->auxchp != NULL)
          auxchfree(csound, ip);

Wow! Just built csound64.dll with your change, tested and working, no more crashes!
You are my hero, thank you so much for solving this so fast!!

But just for curiosity, why the bug affected only Windows??

It didn’t, it was in all systems, but since it was a memory issue, sometimes it did not lead
to crashes.

First Victor fixed it -- I just worked on isolating it.

It was a memory issue and the system implementation of malloc affects the 
exact  way it is manifest.  On windows it crashed, or Linux it apparently 
ran OK but using heavy-duty debugging aids (mainly valgrind) showed there 
was a problem even if it did not crash.  On Mac I suspect the same.  That 
kind of error is the worst to find.

Well isolating it was 99% of the work.
