g++ version 2.96 -- Red Hat Linux
>Description:
A program that uses a stringstream for both input and output get a segmentation fault in _IO_default_uflow_internal when compiled under G++ on Linux.  However, it works fine with compiled under G++ on Solaris.  It also works fine when compiled under Microsoft Visual Studio .NET

Here's a stack trace

State-Changed-From-To: open->closed
State-Changed-By: paolo
State-Changed-When: Sun Oct 27 13:45:47 2002
State-Changed-Why:
    gcc 2.96 is *not* an official GNU release, as such 
    completely unsupported from GNU. See:
    http://gcc.gnu.org/gcc-2.96.html
    If you are able to produce a short self contained
    testcase behaving badly at run-time when compiled by an
    official GNU compiler (i.e., 2.95.x, 3.0.x, 3.1.x, 3.2.x) please open a new PR.
    Thanks, Paolo.
