Under some circumstances, CodeView may still run out of memory while
debugging large applications with the /X switch invoked to take
advantage of extended memory with HIMEM.SYS. The debug information
gets expanded when CodeView loads the program, so the following
suggestions may help the problem:

1. Don't use the quick compile (/qc) option. The symbolic information
   created by the quick compiler may expand much more when loaded by
   CodeView than the symbolic information created by the standard
   compiler. In addition, the quick compiler may create some duplicate
   debug references in the executable file. These duplicate references
   can take up significant memory when CodeView loads the program.

2. Use the CVPACK utility, which is documented in the online
   documentation and on Page 21 of the "Microsoft C Reference" manual.
   CVPACK will compress the debug information in the file by removing
   duplicate references. Use the /P option to achieve maximum
   compression.
