Description Frank Ch. Eigler 2021-05-23 17:19:04 UTC 
glibc 2.32 on f33 has enough extra dwarf complications that a script such as this:

probe process("/lib/libc.so.6").function("*") { println($$parms) }

fails with a couple of different internal errors.  Even if we can't quite grok all the parameter dwarf, we should not abort.
Comment 1 Frank Ch. Eigler 2021-05-23 17:21:22 UTC 
commit 643351d2287b fixes this

The test case is smaller than the original report but covers the two specific error cases found during testing.  (It would generate 10000 probes and GB of compiler mem usage to include the whole thing.)
