The weird thing is that the case runs in 2 win-7 workstations but failed in other 2 win-7 workstations. At the failing workstations it did not print out any call stack when it crashes (I tried with both release and debug PETSc libs), however, win-7 itself popped out a window that says "A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available." Does this mean the program was trying to thing such as writing to reserved memory address?</span></div><div><span></span> </div><div><span>Unfortunately, I can only run the program from command line in the failing workstations since I am not allowd to install VS debuger in
them.</span></div><div><span></span> </div><div><span>Thanks for any info,</span></div><div><span></span> </div><div><span>Qin</span></div><div><br></div> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 12pt;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 12pt;"> <div dir="ltr"> <div style="margin: 5px 0px; padding: 0px; border: 1px solid rgb(204, 204, 204); height: 0px; line-height: 0; font-size: 0px;" class="hr" contentEditable="false" readonly="true"></div> <font size="2" face="Arial"> <b><span style="font-weight: bold;">From:</span></b> "Balay, Satish" <balay@mcs.anl.gov><br> <b><span style="font-weight: bold;">To:</span></b> "Smith, Barry F." <bsmith@mcs.anl.gov>; Qin Lu <lu_qin_2000@yahoo.com> <br><b><span style="font-weight: bold;">Cc:</span></b> petsc-users

> How did it crash? Absolutely nothing printed to the screen, the program just ended? Please send any output. Since it worked on linux it is likely something specific to the windows machine like lack of memory, a compiler bug, …. Does it always crash at
the same place, can you run it in the debugger on the windows machine and where does it end up?<br clear="none">
