Hello,
After updating my system to a 23.0 profile, default/linux/amd64/23.0/split-usr/desktop/plasma (stable), ldconfig has started segfaulting.
Here are the last few lines of "strace ldconfig":
newfstatat(AT_FDCWD, "/usr/lib/rust/lib/librustc_driver-131b866216b2910c.so", {st_mode=S_IFREG|0644, st_size=153456592, ...}, 0) = 0
openat(AT_FDCWD, "/usr/lib/llvm/17/lib", O_RDONLY|O_NONBLOCK|O_CLOEXEC|O_DIRECTORY) = 3
fstat(3, {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
getdents64(3, 0x5555572629d0 /* 22 entries */, 32768) = 824
newfstatat(AT_FDCWD, "/usr/lib/llvm/17/lib/libclang.so.17", {st_mode=S_IFREG|0755, st_size=17506304, ...}, 0) = 0
openat(AT_FDCWD, "/usr/lib/llvm/17/lib/libclang.so.17", O_RDONLY) = 4
fstat(4, {st_mode=S_IFREG|0755, st_size=17506304, ...}) = 0
mmap(NULL, 17506304, PROT_READ, MAP_SHARED, 4, 0) = 0x7fb6eb2d3000
--- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x7fb6ed37c4dc} ---
+++ killed by SIGSEGV +++
Segmentation fault
The file in question (I think), does not look suspicious (I think):
# ls -pal /usr/lib/llvm/17/lib/libclang.so.17 /usr/lib/llvm/17/lib/libclang.so.17.0.6
lrwxrwxrwx 1 root root 18 Jun 25 17:39 /usr/lib/llvm/17/lib/libclang.so.17 -> libclang.so.17.0.6
-rwxr-xr-x 1 root root 14893056 Jun 25 17:39 /usr/lib/llvm/17/lib/libclang.so.17.0.6
The system runs fine (as far as I ca see) but I am a bit nervous about rebooting at the moment.
Any suggestions?
Regards,

The 23.0 profile uses merged /usr as its default. You can, however, remain
with a split /usr for now. What you can't do is mix the two.

I run a merged /usr profile 23.0, and my libclang.so.17.0.6 is bigger:
# ls -la /usr/lib/llvm/17/lib64/libclang.so.17.0.6
-rwxr-xr-x 1 root root 32579024 Jun 2 12:15 /usr/lib/llvm/17/lib64/
libclang.so.17.0.6
Have you re-emerged your toolchain and in particular sys-libs/glibc?

Found the culprit. It was sys-devel/clang
scanelf: /usr/lib/llvm/17/bin/clang-tidy: Invalid section header info (2)
scanelf: /usr/lib/llvm/17/bin/c-index-test: Invalid section header info (2)
scanelf: /usr/lib/llvm/17/lib/libclang.so: Invalid section header info (2)
scanelf: /usr/lib/llvm/17/lib/libclang.so.17: Invalid section header info (2)
scanelf: /usr/lib/llvm/17/lib/libclang.so.17.0.6: Invalid section header info (2)
After re-emerging sys-devel/clang again, ldconfig does not throw a sigsev.

How did you discover this? Was it higher up in the build log?

No, that was while I was "hunting" another issue and run perl-cleaner, then the scanelf lines showed up in the output.
Stange thing is that I did run "emerge --emptytree @world" atleast two times before that.
But now it seems OK and I am happy.
