Is this with the C++ interface, or in Matlab? Are you using 32-bit or 64-bit MinGW?<br>
<br>
If this is in the C++ interface, have you tried building a debug version and running with gdb to see if you can generate a stack trace? If this is in Matlab, there were some bugs I fixed recently that were causing crashes on large problems, when did you last SVN update the Ipopt source?<br>

Subject: [Ipopt] Memory Limit<br>
<br>
Hi,<br>
<br>
What is the maximum size of the problem that can be run on windows?<br>
does the old 2.5 gb windows memory caching limit affect running ipopt by<br>
mingw on a windowds 7 64 bit machine?<br>
<br>
below is the summary of the problem successfully run on ubuntu, however I<br>
can't get the same problem run on windows (the process is killed<br>
automatically, I tried it on multiple machines with ram ranging from 4-16<br>
GB). Any solution to get this run on windows (without the use of<br>
VirtualMachine) is appreciated.<br>
<br>
Regards<br>
<br>
Mosy<br>
