I reported against GWT: https://code.google.com/p/google-web-toolkit/issues/detail?id=8513
As long as gwt does not contain native code, it cannot cause libc free directly. So either heap corruption which is by native code, or something in java reference count misbehaves. Very difficult for byte code within jvm to cause this without native code cooperation.

this is probably native code bug in openjdk.
But I see it in Oracle JDK too.

Caution on upgrading your dev machine to Fedora 20. GWT compilation of "safari" (for Chrome) causes a segfault during the build. Strangely, the build appears to work, so I'm not sure what the net effect of the segfault is.
If you only compile for gecko (Firefox) [the default], you won't see the segfault.
In other words, make clean install-dev PREFIX=$HOME/ovirt-engine DEV_EXTRA_BUILD_FLAGS_GWT_DEFAULTS="-Dgwt.userAgent=gecko1_8,safari" causes the segfault
But make install-dev PREFIX="$HOME/ovirt-engine" works just fine.
I've duplicated this with with both OpenJDK and Oracle JDK.
I can confirm this on my F20 system with OpenJDK as well. So far I have not observed any problems with the resulting build.
I've since duplicated it building a different GWT project, so I'll report the bug against GWT.
I also see a similar crash in Eclipse if Eclipse is using webkit (the default) AND Google Talk is installed. Either uninstalling GTalk or using -Dorg.eclipse.swt.browser.DefaultType=mozilla works around that. So the GWT bug might be a JDK bug. Thoughts?
