me too confused because i tested with different svn revisions
Now - with r7934 (the last).
with msys2 : not compile , see above .
with mingw64: compile fine
but problem with crash is stay :
i take qmc2.exe and all libraries for standalone installation .
All dlls i take from the last mamedev tools. start config from scratch and:
when open tab NOTES - qmc2.exe crashed
open PDF viewers - qmc2.exe crashed
start cached icons - qmc2.crashed.
here upload my build, see, may u found something.http://www55.zippyshare.com/v/pELiRyY1/file.html
