[Libreoffice] [Bug 42865] New: MySQL native driver: free() on non-heap pointer; in debug mode abort()

[Stephan Bergmann]

Lionel,

I must admit I'm confused.  On my system,

That is, libstdc++.so.6 exports the symbol with version GLIBCXX_3.4 and 
libmysqlcppconn.so links against it, while mysqlc.uno.so emits its own 
definition of the symbol (as a local symbol, due to the map file).  Do 
you have an idea why mysqlc.uno.so emits its own definition at all?
