[Roland Mainz]

Hi!

----

We're hitting application (UCRT-based ms-nfs41-client, build with VS2019, on Windows 10, drmemory version 2.6.20167 build 0) crashes under drmemory control like this:
---- snip ----
~~Dr.M~~ WARNING: application exited with abnormal code 0x80000001
C:\Program Files (x86)\Dr. Memory\bin\drmemory.exe exited on WINGRENDEL02 with error code -2147483647.
---- snip ----

Exit code 0x80000001 might be |STATUS_GUARD_PAGE_VIOLATION|.

Does anyone know how to get more information/diagnostics?

----

Bye,
Roland

There are general tips in the docs: https://drmemory.org/page_help.html#autotoc_md12

The DynamoRIO debugging tips also apply with -dr_ops setting those options: https://dynamorio.org/page_debugging.html
