I have a bug in one of my programs that I find particularly
hard to reduce.
I am writing a Windows DLL plugin for the IRC chat client
HexChat (aka XChat). Problem is, all TLS variables, regardless
of type, appear to be initialized to complete rubbish values.
Reading them does not cause an access violation or anything,
but the initial values are garbage. I am initializing the
runtime using the helpers found in core.sys.windows.dll [1].
I wrote a dummy host application in C mimicking the loading
behaviour of HexChat - the TLS variables are initialized
correctly in this case, even though the DLL file is exactly the
same.
What is it that a host application can do to break the TLS of a
D plugin it loads?
