Yes.  But that said, your experience seems to be increasingly common.
I suspect a popular module (DBI?  mod_perl?) has started playing nasty
XS tricks that are confusing Devel::Profiler.

One thing you can try is adding modules to bad_pkgs until the problem
goes away.  Start with anything written in C.  Alternately, write a
package_filter which only tries to profile the modules you're
interested in.  For example, on the Krang project I used a
package_filter that only instrumented modules in the Krang::
namespace.
