Hi David,
With the uprobe-v2 version I only saw one test that appeared to fail because of a sigsegv:
Are you testing on the same hardware? It's conceivable that could make
a difference, especially if the number of CPU's is different.
When searching for ways to test uprobes support I cam across https://github.com/rabinv/uprobes-test . Are these tests useful or have they been orphaned?
Yes, they are very useful. I run them all the time. Note there are
some expected failures late in the run, also apparently these tests do
not test uretprobes.
