Exception 0xc0000094 at pagetest.dll

Some runs fail with “Data is missing” error, caused by IE crash.
Windows error log contains:
“Faulting application iexplore.exe, version 9.0.8112.16421, time stamp 0x4d76255d, faulting module pagetest.dll, version, time stamp 0x531f35b8, exception code 0xc0000094, fault offset 0x0017dd7b, process id 0xdf0, application start time 0x01cf4f6bcc747827”.
Exception and fault offset are always the same.
It is reproducible with IE8 and IE9 EC2 agents.
