Subject [jira] Resolved: (STDCXX-913) inline virtual dtors causing code bloat in exception.cpp
Date Wed, 07 May 2008 21:35:55 GMT

     [ https://issues.apache.org/jira/browse/STDCXX-913?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Martin Sebor resolved STDCXX-913.
---------------------------------

    Resolution: Fixed

[r654286|http://svn.apache.org/viewvc?rev=654286&view=rev] enhances the example program
[{{failure.cpp}}|http://svn.apache.org/viewvc/stdcxx/branches/4.2.x/examples/manual/failure.cpp?revision=654286&view=markup]
to demo these classes. Used it to test the binary compatibility of the fix with 4.2.1 (in
a gcc 4.3.0 15d build).

> Compiling [{{exception.cpp}}|http://svn.apache.org/viewvc/stdcxx/tags/4.2.1/src/exception.cpp?view=markup]
with gcc 4.3 causes the warnings below. We should outline the virtual dtors to reduce the
code bloat.
