I'm talking about static char * some_variable = "hi there"; and in some other file static char * some_variable = "hi there"; the compiler does not know that there are two files containing 'some_variable', and they have to be different variables (someone might change one of them and the other should not change if that happens), but the two "hi there" strings should be shared. How should the compiler represent this in ELF? ------- Comment #40 from geoffk at geoffk dot org 2007-11-05 03:33 ------- Created an attachment (id=14485) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=14485&action=view) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33871
