Summary0031046: Tests - bugs vis bug26139 fails in Win32-configuration due to a lack of memory
DescriptionTest bugs vis bug26139 fails in Win32 configuration with several errors Error: AIS_Shape::ComputeSelection(0) has failed (ACCESS VIOLATION at address 0x00000000 during 'READ' operation) (look at the attached file bug26139.html). But in fact the problem is not in an access violation, an error has happened before it, when memory allocation function NCollection_IncAllocator::Allocate() throws exception due to a lack of memory (only 2 Gb of the virtual memory are available for a process in Win32).
Steps To ReproduceBuild Open Cascade in Win32 configuration, then run command test bugs vis bug26139 -echo in DRAW.

To debug this test case:
  • build Open Cascade in Release with Debug Information configuration
  • turn on breaking on all C++ exceptions in Visual Studio: DebugWindowsException Settings, check the box C++ Exceptions<All C++ Exceptions not in this list>
  • run DRAW
  • attach to the process DRAWEXE.exe using Visual Studio debugger
  • run the following command in DRAW: test bugs vis bug26139 -echo
