Hi,
This might be the issue with the Linux run-time linker’s failure to merge the
ivar guess variables. Can you try with this patch?
http://lists.gnu.org/archive/html/discuss-gnustep/2017-12/msg00129.html
This isn’t needed with the v2 ABI, but I need help fixing the issues with
GNUstep’s NSString implementation before I can recommend enabling that for
GNUstep, because the new NSConstantString representation exposes a lot of bugs
in -base’s unicode string handling.
