You can flush shared pool, optionally, then enable SQL tracing and CBO tracing and check the trace file, anyway you will be asked to do that when you open a tar. What Oracle version do you use?
What's the object you're referencing in your query -- global.client_dim? Is it a [partitioned] table, [m]view or synonym for some other object? -- Vladimir Begun The statements and opinions expressed here are my own and do not necessarily represent those of Oracle Corporation.

And

COUNT(*) ---------- 0
I'm going to open a tar on this. I will email the resolution. ...and check for any more suggestions! :)

There is a contradiction below:

Produces some output.
Your original query does not return anything.
1 SELECT count(*) 2 FROM global.client_dim a 3* WHERE sys_context('userenv','session_user') = trim(a.REPORTS_LOGIN)
The obvious differences here are:
. TRIM function . probably when you've tried to launch the original query you had pofile functions enabled, when you tried it second time it was disabled. . query rewrite is used (could be, right?)
Could you please check the second and third items?
