makepkg corrupts .NET self-contained/ single-file applications in pacman 6.1.0-3

Greetings,

in pacman 6.1.0-3, makepkg corrupts .NET 8.0 self-contained/ single-file applications.

The compiled file present in the final .pkg.tar.zst is much smaller than the original one, and it appears that makepkg strips-away parts of the dotnet application.

Minimal reproduction of the issue

The issue can be re-produced by creating a minimal .NET console application (with dotnet-sdk installed), publishing it as a self-contained sile-file application, packing it as a .tar.gz, and creating a package:

#Install .NET SDK
sudo pacman -S dotnet-sdk

#Create console application
mkdir PacmanRepro
cd PacmanRepro
dotnet new console

#Publish self-contained single-file application and pack
dotnet publish . --output Publish/ --configuration Release --self-contained true -p:PublishSingleFile=true
pushd Publish/
tar -czf ../pacman-repro.tar.gz .
popd

#Create minimal PKGBUILD
tee PKGBUILD >/dev/null << __EOF__
pkgname="pacman-repro"
pkgver="1.0.0"
pkgrel="1"
arch=("x86_64")
options=("!strip")
source=("pacman-repro.tar.gz")
sha512sums=("SKIP")

package()
{
	rm \${srcdir}/\$source

	mkdir -p \${pkgdir}/opt/pacman-repro/
	cp -r \${srcdir}/* \${pkgdir}/opt/pacman-repro/
}
__EOF__

#Create package
makepkg -dsc CARCH="x86_64" Version="1.0.0"

Note: since these single-file applications contain dependencies such as the framework, it is necessary to specify the option options=("!strip") in PKGBUILD.

Observations

• The /opt/pacman-repro/PacmanRepro file in the .pkg.tar.zst is much smaller than the one in pacman-repro.tar.gz, despite the !strip option
• Running the same with pacman 6.0.2-9 does not corrupt the file
• Specifying the options options=("!strip" "!debug") in PKGBUILD also does not corrupt the file, it looks like with the default debug enabled, the file is actually stripped even with !strip specified

PS: for easier repro without having to install .NET, please find attached a pre-compiled pacman-repro.tar.gz here, so that the first few steps above can be skipped.

Keep up the great work and all the best
