BUG# 9703 (4.20.50)
SYMPTOMS
While executing multiple calls to dbconvert() that convert a character string to a DBDATETIME value, an error number 10000 message occurs:
Unable to allocate sufficient memory
CAUSE
Conversion of character string values to DBDATETIME variables can result in gradual memory leakage within DB-Library. DB-Library memory in a Windows or medium-model MS-DOS application will be exhausted after approximately 3500 calls to dbconvert(). DB-Library applications compiled for Windows NT, large-model MS-DOS and OS/2 will be less affected as the maximum heap size is much larger in these environments.
WORKAROUND
This behavior occurs with DB-Library version 4.20.32 and later. The problem will not occur using DB-Library 4.20.00 and 4.20.21.
STATUS
Microsoft has confirmed this to be a problem in DB-Library version 4.20.50. This problem was corrected in DB-Library version 4.21.00. For more information, contact your primary support provider.
