Symptoms
During insert into table with long raw / LOB columns using bind variables, the following errors could occur:
ERROR
ORA-7445 in memmove()
ORA-7445 in memcpy()
ORA-600 [kghstack_alloc]
Looking at the call stack, we see the function kdlwdb() present near the top, eg.:
... memmove kdlrdo kdlwdb kdlwfb kdl_write1 koklicbf ...
From the cursor dump in the trace file, we may see something like the following for one of the bind variables:
Bind#1
oacdty=23 mxl=2000(2147483647) oacdty=23 --> long raw
kxsbbbfp=9fffffffbf24f bln=2000 avl=-269 ---> negative length
