https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D235751 --- Comment #8 from Dennis Clarke <dclarke@blastwave.org> --- (In reply to Konstantin Belousov from comment #7) What precisely did you do? I see no way that you made this work just fine on a 14.0-STABLE system when it fails in the same way on 13.4-RELEASE-p1 machine :=20 $ uname -apKU=20 FreeBSD dasoyva 13.4-RELEASE-p1 FreeBSD 13.4-RELEASE-p1 GENERIC amd64 amd64 1304000 1304000 $ freebsd-version -kru=20 13.4-RELEASE-p1 13.4-RELEASE-p1 13.4-RELEASE-p2 $=20 $ which cc /usr/bin/cc $ CC=3D/usr/bin/cc $ export CC $=20 $ $CC --version FreeBSD clang version 18.1.6 (https://github.com/llvm/llvm-project.git llvmorg-18.1.6-0-g1118c2e05e67) Target: x86_64-unknown-freebsd13.4 Thread model: posix InstalledDir: /usr/bin $ $ $CC -std=3Diso9899:1999 -pedantic -pedantic-errors -m64 -g -O0 -fno-built= in -shared -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=3D64 -D_XOPEN_SOURCE=3D600 -D_REENTRANT -o t1.so -fPIC t1.c $ $CC -std=3Diso9899:1999 -pedantic -pedantic-errors -m64 -g -O0 -fno-built= in -shared -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=3D64 -D_XOPEN_SOURCE=3D600 -D_REENTRANT -o foo t2.c t1.so $ file foo foo: ELF 64-bit LSB shared object, x86-64, version 1 (FreeBSD), dynamically linked, for FreeBSD 13.4, with debug_info, not stripped $ readelf -delV foo | grep -E 'NEED|NAME|PATH' 0x0000000000000001 NEEDED Shared library: [t1.so] 0x0000000000000001 NEEDED Shared library: [libc.so.7] 0x000000006ffffffe VERNEED 0x340 0x000000006fffffff VERNEEDNUM 1 $ ./foo Segmentation fault (core dumped) $ LD_LIBRARY_PATH=3D`pwd` ./foo Segmentation fault (core dumped) $=20 So you are saying that, with magic, the problem goes away on a 14 STABLE=20 machine and then returns everywhere else? --=20 You are receiving this mail because: You are on the CC list for the bug.=
