--- Comment #18 from minion <minion.procyk at gmail.com> ---
gave it another shot running this under kernel 4.18.2 using wine-4.0 stable w/o
dxvk and i still get no window launching. I'm also not smart enough to dork
around with ptrace under wine. I couldn't get any log lines that would help
hint at the issue. Taking a guess i'd say we're not providing the correct
buffer and/or offsets for PTRACE_POKEUSER

There are lots of type conversions being done like unsigned longs being passed
to methods requiring signed longs and vice versa, longs being passed as int
parameters. I have very little experience with C and C++ so I'm not sure if
these are potential issues or not. 

I'd be interested to see someone shed a little light on this. I dorked around
for a bit with no change. Will be happy to help where i can.
