Alpaca fails to build - module python3-lxml: child process terminated with exit code 137

Hi there,

I am facing issues to build Alpaca on my machine (using GNOME Builder). It throws

[...]
building 'lxml.objectify' extension
  x86_64-unknown-linux-gnu-gcc -O2 -pipe -g -Wp,-D_FORTIFY_SOURCE=3 -Wp,-D_GLIBCXX_ASSERTIONS -fexceptions -fstack-protector-strong -grecord-gcc-switches -fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer -fPIC -DCYTHON_CLINE_IN_TRACEBACK=0 -I/usr/include/libxml2 -Isrc -Isrc/lxml/includes -I/usr/include/python3.12 -I/usr/include/x86_64-linux-gnu/python3.12 -c src/lxml/objectify.c -o build/temp.linux-x86_64-cpython-312/src/lxml/objectify.o -w
Error: module python3-lxml: child process terminated with exit code 137

and fails to compile. Version 6.1.x built flawlessly, this issue only came up in version 7 and onward for me.

Thanks in advance!

make sure the lxml module is in the json you are using to compile

{
            "name": "python3-lxml",
            "buildsystem": "simple",
            "build-commands": [

            ],
            "sources": [
                {

            ]
        },

It is, I've used a fresh clone of Alpaca. The build error is quite obscure, so I don't really know where to start debugging... I'd love to help out with a few issues, but without being able to build, that's close to impossible :(
