Most of this is just withCoreFile right? The only difference is the part where it also reads the stderr? If so we should probably just modify withCoreFile to call CombinedOutput() and return it.

Thanks for the suggestion. I updated withCoreFile to call CombinedOutput, and then removed all the noise in the new test. Way cleaner for sure.
Without this fix, stack traces from linux/arm64 core dumps showed SP values that differed from the runtime's panic output. Fixes go-delve#3591

This patch adds a reproducer based on the original snippet from the issue and a test that tries to verify if the SP is the same.
Fixes #3591
