Crash with nearly empty program compiled via yasm/nasm.

I've been trying to isolate another issue and stumbled upon another issue where running a nearly empty program will just crash DynamoRIO without any logs or messages. I've tried to attach the debugger but it seems I'm unable to catch the exception.

To reproduce the issue I did following:
```
bits 64
global main

section code exec
main:
; Exit
xor eax, eax
ret
```
Compile above code with NASM or YASM
```
yasm.exe -f win64 -o input.obj input.asm -debug
```
Link with MSVC linker
```
link.exe input.obj /OUT:output.exe /entry:main /debug /LARGEADDRESSAWARE:NO /DYNAMICBASE:NO "Libs\x64\kernel32.lib"
```
And running it with DynamoRIO
```
drrun.exe -verbose -debug -- output.exe
```
I've tested following versions and all are affected:
```
DynamoRIO-Windows-7.1.0-1
DynamoRIO-Windows-7.91.18145-0
DynamoRIO-Windows-7.91.18151-0
```
Also the compiled binary to make things a little easier: [output.zip](https://github.com/DynamoRIO/dynamorio/files/3621127/output.zip)
