----------------------------------------
Summary: Janitor<BinInputStream>::~Janitor() throws in unwind
Key: XERCESC-2031
URL: https://issues.apache.org/jira/browse/XERCESC-2031
Project: Xerces-C++
Issue Type: Bug
Components: Utilities
Affects Versions: 3.1.1
Environment: Solaris 10, x86
Reporter: Jimmie Högklint
If PosixFileMgr::fileClose() receives an invalid file handler or if its unable
to close a file handler it will throw an exception. If this is done in an
unwind of, for example, Janitor<BinInputStream> noone is around to catch that
exception before the process is terminated. (Leaving a destructor with a throw
during unwind is rewarded with termination of the process)
This happens when variable "streamJanitor" goes out of scope in
ReaderMgr::createReader(...)
Callstack looks like this:

This applies to WindowsFileMgr as well.
If additional information is needed I'm happy to provide it.
