--- Comment #11 from Evangelos Foutras <evangelos at foutrelis dot com> --- Created attachment 11174 --> https://sourceware.org/bugzilla/attachment.cgi?id=11174&action=edit Test case with Arch's and Debian's GCC-provided crt{begin,end}.o (In reply to nsz from comment #10) > i'd try to verify that the right ld is used (e.g. strace -f -e execve > musl-gcc ...) > then i'd try to reproduce the issue outside of musl-gcc (e.g. manually > invoking > ld with the options seen in the strace and look for the NOTE program header) Thanks for the suggestion. I was able to reduce my test case to something that is reproducible on both Arch and Debian. The attached test case indicates that it's some difference between Debian's and Arch's crt{begin,end}.o (as provided by GCC) that's causing ld to add the NOTE program header and .note.gnu.property section to the produced binary. Comparing them using 'objdump -h', I notice that Arch's crt{begin,end}.o have a .note.gnu.property section and Debian's don't. If I use 'objcopy -R .note.gnu.property' on the Arch ones, then those produce a working executable too! Does the above indicate that the fix to binutils needs to be tweaked? ================================= [pr23428-test]$ make cc -c -o test.o test.c ld -static -o test-arch arch-crts/* arch-musl/* test.o ld -static -o test-debian debian-crts/* arch-musl/* test.o pr23428-test$ grep gnu.property test-* Binary file test-debian matches [pr23428-test]$ ./test-debian [pr23428-test]$ ./test-arch Segmentation fault (core dumped) [pr23428-test]$ objcopy -R .note.gnu.property arch-crts/crtbegin.o [pr23428-test]$ objcopy -R .note.gnu.property arch-crts/crtend.o [pr23428-test]$ make -Bs test-arch [pr23428-test]$ gdb -q -ex run ./test-arch Reading symbols from ./test-arch...(no debugging symbols found)...done.
