Comment (by pospeselr):
To any future code archaeologists or devs having to deal with similar COM
or IA2 problems when using the mingw toolchain, here's a couple tools for
you:
ia2_test: https://github.com/pospeselr/ia2_test
This is basically a fake screen-reader. It grabs the IAccessible object at
a given point in screen-space, and recursively iterates over all the
children calling IA2 APIs. Not all the APIs are covered (as I stopped
implementing calls when screen readers stopped crashing Tor Browser) but
is easy enough to add more.
mingw_com: https://github.com/pospeselr/mingw_com
A standalone mingw-based project for construction a COM client, proxy and
server. I used this briefly as a minimal COM test-bed for reproducing
marshaling related crashes. Should note that the project as is will
compile but will fail at runtime with the current stock version of mingw.
