--- Comment #2 from Simon Sobisch <simonsobisch at gnu dot org> --- looks like the error comes from name resolution and is also reproducible with a much more simple Program-id. NofBug. Data division. Working-storage section. 01 billTo. 10 name pic x(30). Procedure division. m. Move 'Robert Smith' to name of billTo Goback . Can someone please change the bug title to "SIGSEGV when using qualified names" and increase importance (that's a core part of the language)?
