I can also report the same abort occurs with a different target: character(len=:), target, allocatable :: name6 the difference being allocatable length vs. fixed length.

gcc is 8.2.0 from msys2, wx is from msys2, but this happens with any version of wx in any configuration.

What's the output of gcc -v command? Which version of WX? How you install it? Using pacman? What the WX build configuration (gcc_dll\mswu\build.cfg)? or options passed to after mingw32-make -f makefile.gcc when build WX?
