_From [ldpatchg...@gmail.com](https://code.google.com/u/111648904502169464665/) on August 13, 2014 21:26:14_

For the Summary, please follow the guidelines at https://code.google.com/p/dynamorio/wiki/BugReporting and use one of the CRASH, APP CRASH, HANG, or ASSERT keywords What version of DynamoRIO are you using? DynamoRIO-Windows-4.2.2763-42

Does the latest build from http://build.chromium.org/p/client.dynamorio/builds/ solve the problem? No

What operating system version are you running on? Windows7 32bits

What application are you running? dr_crash_xchgesp.exe

Is your application 32-bit or 64-bit? 32bits

How are you running the application under DynamoRIO? drrun dr_crash_checksum.exe

What happens when you run without any client? DynamoRIO delivered a unexpected exception to target code

What happens when you run with debug build ("-debug" flag to drrun/drconfig/drinject)?

What steps will reproduce the problem?

1.drrun dr_crash_checksum.exe
2.
3.

What is the expected output? What do you see instead? Is this an application crash, a DynamoRIO crash, a DynamoRIO assert, or a hang (see https://code.google.com/p/dynamorio/wiki/BugReporting and set the title appropriately)?

_Original issue: http://code.google.com/p/dynamorio/issues/detail?id=1511_

Start by reproducing `drrun dr_crash_checksum.exe` on the reported 32-bit Windows 7 setup using the attached `dr_crash_checksum.exe`, then compare it with execution without DynamoRIO and with the `-debug` flag. Done means identifying why drrun delivers an unexpected exception to the target and documenting or fixing the behavior with a reproducible validation.
