Hi,

I'm trying to debug a problem with Octave running under
Cygwin for Windows ME.

Every time I fork, I get a message box for each dynamically
loaded dll saying:
   Octave has caused an error in SUB.DLL
   Octave will now close.
This does not happen in Windows 2000.

The following code demonstrates the error:

--- dynmain.cc:
#include <iostream>
#include <windows.h>
int main(int argc, char *argv[])
{
 HINSTANCE handle = LoadLibrary("dynsub.dll");
 std::cout << "# Calling fork\n";
 std::cout << (fork()?"parent\n":"child\n");
 return 0;
}

--- dynsub.c:
#include <stdio.h>
void dynsub(void) { printf("in dynsub\n"); }

--- Makefile:
all: dynsub.dll dynmain.exe
dynmain.exe: dynmain.cc  ; g++ -o $@ $<
dynsub.dll : dynsub.c   ; gcc -shared -o $@ $<

I updated my cygwin distribution as of this morning (Feb 2, 2003) and
the problem persists.
