Tino has proposed merging lp:~widelands-dev/widelands/gcc_optimize into
lp:widelands.
Requested reviews:
Widelands Developers (widelands-dev)
For more details, see:
https://code.launchpad.net/~widelands-dev/widelands/gcc_optimize/+merge/331049
On my system gcc 7.2 (Win10 x64, GCC 7.2 MinGW) still produces corrupt binaries
with -O3.
The economy test fails and crashes.
Can anyone reproduce this on another OS?
