Hi, here is a complete (but not minimal, sorry, it takes a while to build)
reproducer:

> git clone https://github.com/graalvm/mx
> git clone https://github.com/oracle/graal
> cd graal/vm
> ../../mx/mx fetch-jdk -A --jdk-id labsjdk-ce-latest
> export JAVA_HOME=$HOME/.mx/jdks/labsjdk-ce-latest
> ../../mx/mx --env ce-python build --dep PYTHON_JAVA_STANDALONE_SVM_JAVA24
> # The binary is now here:
> # 
> ../sdk/mxbuild/linux-amd64/PYTHON_JAVA_STANDALONE_SVM_JAVA24/graalpy-community-24.2.0-dev-linux-amd64/bin/graalpy

I can then reproduce the error like this:

> gprofng collect app -o pythonsegv.er 
> ../sdk/mxbuild/linux-amd64/PYTHON_JAVA_STANDALONE_SVM_JAVA24/graalpy-community-24.2.0-dev-linux-amd64/bin/graalpy
>  -c 1
> gprofng display text -functions pythonsegv.er
