Auto merge of #97085 - rylev:test-issue-33172, r=wesleywiser

Add a test for issue #33172

Adds a test confirming that #33172 has been fixed.

CDB has some surprising results as it looks like the supposedly unmangled static's symbol name is prefixed when it shouldn't be.

r? `@wesleywiser`

Closes #33172
