Can you give me a complete list of steps for reproducing this, including
the exact versions of OpenJDK and Fedora you're using, as well as the
command you used to build OpenJDK?

Thanks.

I finally had a chance to set up a Fedora system to reproduce this.
Here's what I discovered:

* specifying "use-lto=false" to make fixes the problem

* a Google search for the message doesn't tell me much, except that using
gold instead of the default linker may help:
https://developer.mozilla.org/en-US/docs/Building_Firefox_with_Address_Sanitizer

* the same "unresolvable ..." message is printed on Debian Wheezy, but it
doesn't cause linking to fail

My guess is that it's a bug in GCC's link time optimization, so I
recommend disabling LTO when you build, e.g.:

make openjdk=/home/max/jdk7/latest/build/linux-amd64/j2sdk-image
openjdk-src=/home/max/jdk7/latest/jdk/src use-lto=false
