[pkgconf] Segmentation Fault when running the binary

[aabellagm]

Describe the bug
The pkgconf binary crashes (Segmentation Fault) in Fedora 41. That causes errors when building other packages, like ffmpeg.

Environment

• OS: Fedora 41
• Compiler: gcc 14.2.1

To Reproduce
Steps to reproduce the behavior:

1. ./vcpkg install pkgconf
2. ./installed/x64-linux/tools/pkgconf/pkgconf --version
   Segmentation fault (core dumped)

Expected behavior
The command above should just run and print the version and it also should allow ffmpeg to be correctly built.

Additional context

• It fails in a VM and in Docker
• ldd command ends with error code 1 without printing anything.
• The binary in packages directory fails in the same way. The one in the buildtrees works as expected.
• Setting set(VCPKG_FIXUP_ELF_RPATH OFF) in the triplet solves the pkgconf problem, but it would be desirable
• In case it helps, the output when using pkgconf while building ffmpeg:

Do you use system patchelf or vcpkg patchelf? If it comes from the system, could you try with --x-abi-tools-use-exact-versions?

[aabellagm]

I don't have patchelf installed in my system, so I guess it is using the one in VCPKG.
I installed it, just in case it makes any difference, but nop, pkgconf crashes in the same way, with and without --x-abi-tools-use-exact-versions

@aabellagm, Thanks for posting this issue, We don't have a Fedora environment at the moment. I haven't reproduced your error in my own Linux environment.
