LocalFileFormatTarget dtor may throw an exception
-------------------------------------------------
Key: XERCESC-1898
URL: https://issues.apache.org/jira/browse/XERCESC-1898
Project: Xerces-C++
Issue Type: Bug
Components: Miscellaneous
Affects Versions: 3.0.0, 3.0.1
Reporter: peter
The destructor of LocalFileFormatTarget is calling flushBuffer() which in turn
may throw exceptions. Throwing exceptions in dtor however is dangerous since it
may lead to program termination if the exception is thrown during stack unwind.
Example: DOMLSSerializer::writeToURI() is causing imediate program termination
if there is no space left on disk. The reason is an exception thrown in
DOMLSSerializer::write(). During stack unwind the dtor of LocalFileFormatTarget
is called throwing another exception which is illegal and leads to program
termination.
Example stacktrace from real world application:
