Attached is a patch for quantal.

I have built a fix for testing in my PPA here:
https://launchpad.net/~christopherarges/+archive/ppa-test/+sourcepub/2614914/+listing-archive-extra

I've been able to run the testcase in #1 and before it results in NaN,
and after the patch I see 0.

** Changed in: eglibc (Ubuntu Quantal)
       Status: Confirmed => In Progress

** Patch added: "fix_lp1000498_quantal.debdiff"
