Dr Watson crash dump

To reproduce:
 - open http://public.tableausoftware.com/views/Book11_11/Sheet1?:embed=yes&:toolbar=yes&:tabs=no
 - On some machines it will immediately crash.  On others it requires a bit more work...
 - Perform some actions on the page that cause it to redraw.  For example repeatedly select different bars in the chart.  Re-sort the chart using the x-axis sorting indicator.

Unfortunately this issue does not reproduce on all machines.  Here's what I've tried that might help to narrow things down a bit:
 - I was able to reproduce on XP, Vista, and Win7 but only on machines with < 3GB RAM.  I could not reproduce this on Mac or iPad. 
 - Having the browser window full screen (or large at least) seems to cause the issue to happen more often.
 - This issue shows up in Safari (5.1.2) as well as the nightly build from 2012-03-06.

Attached are the Dr. Watson crash logs from one case.

Please let me know if I can provide any other detail.

Dr Watson crash log

The user.dmp file attached is from a crash of DefWatch.exe (Symantec AntiVirus), so that doesn't match this crash.

The attached log file has many, many crashes listed. There are several WebKit2WebProcess.exe crashes, which must be the ones you're referring to.

These crashes are under the MS C Runtime Lib malloc, likely due to a corrupt heap.

I can't repro this on Win7 x64 with gflags full page heap enabled.
