Description
**Describe the bug**
When I run `notepad++` [64 bit latest ](https://notepad-plus-plus.org/downloads/v8.1.9/) it crashes immediately
**To Reproduce**
Steps to reproduce the behavior:
1. Install [Notepad++](https://notepad-plus-plus.org/downloads/v8.1.9/)
2. Run with `drltrace.exe`:
```
.\drltrace.exe 'c:\Program Files\Notepad++\notepad++.exe''
```
3. Exact output or incorrect behavior.
Launch the app under drltrace without the crash
Please also answer these questions drawn from https://drmemory.org/page_help.html#sec_narrow :
- Does the problem go away when running in light mode (pass `-light` to Dr. Memory)?
- Doesn't apply
- Does the problem go away when running with the options `-leaks_only -no_count_leaks -no_track_allocs`?
- Doesn't apply
- Does the problem go away when running under plain DynamoRIO? Do this by running `dynamorio/bin32/drrun -- ` or `dynamorio/bin64/drrun -- ` depending on the bitwidth of your applicaiton. (Ignore warnings about "incomplete installation".)
- yes, under plain DynamoRIO the app launches and works.
- 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?
**Expected behavior**
To run Notepad++ under drltrace
