Boris Kolpackov updated XERCESC-1898:
-------------------------------------
Fix Version/s: 3.1.0
Assignee: Boris Kolpackov
I think doing a catch-all and ignoring any exception would be a reasonable
strategy in this situation.
> 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
> Assignee: Boris Kolpackov
> Fix For: 3.1.0

>
> 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.
