------------------------------------------
Whoa, that was fast!
I applied the patch on top of xercesc 3.1.1 and it works fine. Thanks
> 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
> Assignee: Alberto Massari
> Fix For: 3.2.0
>
>
> 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:
