[jira] Created: (STDCXX-913) inline virtual dtors causing code
bloat in exception.cpp
inline virtual dtors causing code bloat in exception.cpp
--------------------------------------------------------
Key: STDCXX-913
URL: https://issues.apache.org/jira/browse/STDCXX-913
Project: C++ Standard Library
Issue Type: Bug
Components: 27. Input/Output
Affects Versions: 4.2.1
Environment: gcc 4.3.0
Reporter: Martin Sebor
Assignee: Martin Sebor
Priority: Minor
Fix For: 4.2.2
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.

[jira] Resolved: (STDCXX-913) inline virtual dtors causing code
bloat in exception.cpp
Posted by "Martin Sebor (JIRA)" <ji...@apache.org>.
[ 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).
