Problem IC80616
|
Status: Closed |
Crash in SQL PL associative arrays when allocating memory for new array elements |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
When using SQL PL associative arrays the DB2 instance may crash
with a segmentation fault (signal #11 on Unix/Linux) or memory
access violation (C0000005 on Windows) with the following stack:
<redBlackTree::rbGetFirstNode>
<associativeArrayHeader::getFirstNode>
<associativeArrayHeader::getFirstIndex>
<sqlriArrayDescriptor::destroyAllChildren>
<sqlriArrayDescriptor::allocateDyn>
<sqlriArrayDescriptor::setElement>
<PVM::setArrayElement>
<PVM::run>
<pvm_entry>
<sqloInvokeFnArgs>
<sqlriInvokerTrusted>
<sqlriInvokeInvoker>
<sqlricall>
<sqlriSectInvoke>
<sqlrr_process_execute_request>
<sqlrr_execute>
<sqljs_ddm_excsqlstt>
<sqljsParse>
<sqljsSqlam>
<sqljsDriveRequests>
<sqljsDrdaAsInnerDriver>
<sqljsDrdaAsDriver>
<sqeAgent::RunEDU>
<sqlzRunEDU>
<sqloInitEDUServices>
This issue is caused by a logic problem during the error
handling of a failure to allocate memory from the application
heap for new elements in a SQL PL associative array.
This APAR will fix the error handling to remove the crashing
conditions such that the correct memory allocation failure
message (such as SQL20442) will be returned. |
