Today while sifting through Mac crash data, I see an awful lot of crashes like this:

https://crash-stats.mozilla.com/report/index/a490061f-cba0-48a4-9959-9191d2100928
https://crash-stats.mozilla.com/report/index/fb76bb39-60d3-44c0-8e94-d76952100928
https://crash-stats.mozilla.com/report/index/f4b3c40d-81aa-4a37-94c3-871e52100927

Some are running the 20100928 build but I see other build IDs as well.

I don't seem to see this when I do a similar query of Windows crashes in the last day: http://tinyurl.com/26x5jdk

Yeah, that's because those mac crashes are 64-bit (Note the CPU is amd64), and we don't have real 64-bit Windows builds yet. The spike is probably because we updated everyone on the old ppc/x86 universal binaries to the new x86/x86-64 universal binaries, so more people wound up running a 64-bit nightly.

The lack of a signature is probably mostly a dupe of bug 571578. The 64-bit stackwalker in Breakpad doesn't try as hard as the 32-bit one to find caller frames when it doesn't know anything about the current frame (like when we're in JITted code).
