CRASH running MercTactics.exe on Win10-1903

[lefty2]

When I try to use dr. memory on Windows 10 I get this error:

As already requested (!!! https://github.com/DynamoRIO/drmemory/issues/2232#issuecomment-712485938) please fill out the bug template. Without more information this report is not actionable.

I ran with all the below options and it crashes just the same way with the same error messages above.

• Does the problem go away when running in light mode (pass -light to Dr. Memory)?
• Does the problem go away when running with the options -leaks_only -no_count_leaks -no_track_allocs?
• Does the problem go away when running under plain DynamoRIO? Do this by running dynamorio/bin32/drrun -- <application and args> or dynamorio/bin64/drrun -- <application and args> depending on the bitwidth of your applicaiton. (Ignore warnings about "incomplete installation".)
• What happens with the debug version of Dr. Memory and of its underlying engine DynamoRIO? Try this by passing -debug -dr_debug -pause_at_assert. Are any messages reported?

[lefty2]

I'll attach the executable that I'm using, so you can try for yourself http://astronautz.com/MercTactics/debug.7z

That is impossible: dynamorio/bin32/drrun is not Dr. Memory and cannot produce the same message.

Given no other provided info, we have to assume that all other applications work fine on this same machine, and that this is something that only happens with this particular "MercTactics" executable.

[lefty2]

This is the exact message that drrun gives:

DynamoRIO Notice: C:\backup\warlord\Warlord\debug\MercTactics.exe(8844)

I also tried running on an application compiled with GCC and it crashes the same way. Dr. memory runs this application fine on Windows 8.1, so it's looks more like this version of Windows 10 that's causing the problems

This is not true. I tried with several other applications and they all have the same problem

But why file an issue on a large complex executable "MercTactics" if it reproduces with a tiny hello,world executable? Always minimize before filing, and describe the context in the filing.

If hello,world crashes under plain DR, there is likely some invasive software on this particular machine causing interoperability problems. Certainly simple apps work on Windows 10 1903 on other machines. Most likely this requires attaching the debugger on the machine where this reproduces and getting a callstack, and looking at what security or anti-virus or other software may be causing the problem by injecting libraries into every process that hook or otherwise clobber code.

[lefty2]

I see a lot of similar crash bugs filed here, so it appears it's not just my app that has a problem. Also, as I said dr. memory works perfectly with my app on Windows 8.1. I disabled the Anti virus. I don't know how you come to the conclusion that something is "injecting libraries into every process that hook or otherwise clobber code", this is just a vanilla install of Windows 10.
