If somebody has seen this before, maybe you could point me the right direction
cross compiling VLC for window 64 bit from debian. I have been successful at 32 bit (i686-w64-mingw32) but when I attempt windows 64 bit cross
compile I keep getting the same error stream

Research seem to indicate that this is a gcc bug that surfaced in 2016.
https://github.com/Alexpux/MINGW-packages/issues/1580
I have just upgraded to debian version buster which has the gcc version 7 and all latest patches but I still get the error. I have to believe I'm not the first to see this, I have a new machine built expressly for the purpose with standard installs of all required software, including lib64itm1. as mentioned previously, win32
compile was successful in this environment.
Thank you in advance for any pointers.
