The FreeBSD-clang package on amd64 contains libclang_rt.asan-i386.so, which links to the 32-bit version of libgcc_s.so.1. It is not clear if that file belongs in FreeBSD-clang or if it should be placed into a different package. For unknown reasons, pkg *sometimes* recognizes this and decides that it needs to install a package to supply libgcc_s.so.1:32. In particular, when we initially install the VM with 'pkg install [long list of FreeBSD-* packages]', pkg does not recognize that it wants this; but the *next* time 'pkg install' runs, it decides that it needs libgcc_s.so.1:32 -- even though that particular library is not needed by the particular package we're trying to install -- and goes looking for it... and ends up picking gcc12-devel as a provider. Later in the EC2 image building process, we run 'pkg autoremove' (which was added during 15.0 to get rid of the "bogus dependencies" which were added while installing other packages) and pkg is once again confused: It decides that gcc12-devel is an automatic port which is not required by anything else, but upon determining that it should be removed it then determines that FreeBSD-clang depends upon a port which is being removed and deletes FreeBSD-clang as well. It's not clear what is breaking in pkg, but as a temporary workaround add the FreeBSD-clibs-lib32 package to the "small" and "builder" EC2 image flavours in order to satisfy the libgcc_s.so.1 demand. This commit should be reverted if libclang_rt.asan-i386.so moves out of FreeBSD-clang, (i.e. if it becomes possible to install a 32-bit-free amd64 system) or when the pkg issue is resolved (i.e. pkg consistently recognizes the shared library dependency and installs clibs-lib32 automatically as a FreeBSD-clang dependency).

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
