Roger Leigh commented on XERCESC-2154:
--------------------------------------
How exactly did you build Xerces-C++? Did you use the Autotools configure
script, or the CMake build? Would it be possible to test with the other to see
if this makes any difference?
With the change to the standard libraries, is there any possibility that the
exception isn't being caught due to some problem with typeinfo or exception
handling? (I've seen this with GCC on FreeBSD with different libgcc versions
in base and ports.) Is this a possibility on Solaris?
By setting the error codes to different values, your _xml_broken.xml_ example
sets the _retval_ to 4 on line 602 of _samples/src/DOMPrint/DOMPrint.cpp_. For
this codepath to run, _errorsOccured_ must be set to true in one of the catch
blocks above. On Linux, this works correctly testing locally. On your system,
this uncaught exception can only occur if a thrown exception was not handled by
_any_ of the catch blocks, including *catch(...)*. This indicates something is
very wrong with the exception handling on your system with this build of
Xerces-C++.

> Hi,
> I have a problem running xerces on Solaris x86 platform compiled with
> '-std=c++11' flag using Oracle developer studio 12.6. The compilation is fine
> and the library works fine in all positive scenarios, but it fails with Abort
> signal (core dumped) when an XML content to process is broken ending with the
> error message:
> "terminate called after throwing an instance of 'xercesc_3_2::XMLErrs::Codes'"
> I was able to isolate the problem by using DOMPrint example run with a file
> with an invalid xml content.
