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.

I wouldn't expect those options to make a difference for uprobes. Theymight for kprobes.


I just finally found the bug in ARM uretprobe's.  It's a simple fix.
