Summary0000608: Possible CC of "Compile bug: internal compiler error: Segmentation fault #20083"
DescriptionAlmalinux 10.1 on ppc64le (IBM Power 10) - Attempting to build llama.cpp fails with Internal Compiler Error.

May be similar to https://github.com/ggml-org/llama.cpp/issues/20083
Steps To ReproduceTry building current llama.cpp after git cloning, fails.
