[Bug libgcj/20727] New: double free or corruption

["green at redhat dot com" <gcc-bugzilla at gcc dot gnu dot org>]

When I run a sample jogl application with gcj, I get the following at the end....

Program received signal SIGABRT, Aborted.

I don't have a simple test case yet.  I will provide one once we have a jogl
that builds reliably.  Just thought I'd file this in the meanwhile...
