However 'ar tv' and 'ar x' think it is a 100MB file which is incorrect. This happens because print_arelt_descr(), print_contents() and extract_file() use 32bit size_t variables instead of bfd_size_type ones. -- 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

http://sourceware.org/bugzilla/show_bug.cgi?id=14156 --- Comment #3 from H.J. Lu hjl.tools at gmail dot com 2012-06-27 17:35:31 UTC --- (In reply to comment #0) I'm not sure what the right fix for this is, but I think the linker scripts should do something to ensure that sections which are pieced-together in a particular link order (init/fini and probably also ctors/dtors, and perhaps others) never get reordered. If that's not possible, then this option should be documented as dangerous/broken so that projects don't put it in their makefiles. ctors/dtors sections contain pointers. The behavor of their order is undefined. -- 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
