Summary:
SYMPTOMS
In Microsoft C versions 5.1, 6.0, 6.0a, 6.0ax, and C/C++ version 7.0,
a program that does an INT 21H function 67H to increase the per-
process file handle count and then uses one of the exec family of
functions (including spawn with P_OVERLAY), may hang later in the
program because of memory corruption.
STATUS
Microsoft has confirmed this to be a problem in versions 5.1, 6.0,
6.0a, 6.0ax, and C/C++ version 7.0 of the C compiler. We are
researching this problem and will post new information here as it
becomes available.
More Information:
This has also been reported when calling COBOL 3.0 or 3.0a from C. If
the COBOL function uses ISAM files, the IXSIO function (COBOL's
support module for ISAM's) will cause C to think that interrupt 21H
function 67H was invoked and the program will hang.
