Something is wrong with GNU_RELRO segment in libpthread-2.7.so: 1. Why is p_filesz != p_memsz? 2. What does p_filesz > p_memsz mean? I got GNU_RELRO 0x016bc8 0x0000000000216bc8 0x0000000000216bc8 0x0003d0 0x0003c0 R 0x1 ... 08 .ctors .dtors .jcr .data.rel.ro For libpthread-2.7.so in Fedora 8, I got GNU_RELRO 0x015ba8 0x0000003035015ba8 0x0000003035015ba8 0x000458 0x000458 R 0x1 ... 08 .ctors .dtors .jcr .data.rel.ro .dynamic .got Please provide ALL inputs used to create the bad libpthread-2.7.so. -- http://sourceware.org/bugzilla/show_bug.cgi?id=6494 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-binutils
