It is possible, but will break function pointer comparisons if a pointer to foo is passed between the shared lib and executable in either direction, since the address of foo in the shared lib and the address of the same foo in the executable will be different. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
