Boris Kolpackov closed XERCESC-1845.
------------------------------------
Resolution: Cannot Reproduce
Assignee: Boris Kolpackov
I am closing this issue for two reasons: (1) seeing that the same code works
fine on GNU/Linux and Windows, it is probably a problem with Purify on Solaris
rather than Xerces-C++ code; (2) none of the active developers have access to
Purify on this platform to try to reproduce the problem. If someone is capable
and willing to investigate this further, feel free to reopen this issue.

> This only occurs on a Sun Sparc using SunPro CC 5.0. Xerces works fine on
> Linux and Windoze. This is from the 3.0.0 tarball build.
