Testcase for BZ 28519

[Joe Simmons-Talbott <joetalbott@gmail.com>]

Hi,

I'm trying to write a testcase for BZ 28519 but not having much luck.
My testcase is below.  For a simple application that calls
'system("-echo")' I get the same behavior as the BZ but for the testcase
I get the expected behavior where sh fails to find "-echo".

Does anyone have any thought on what I might be missing?

Thanks,
Joe

My testcase looks like this:
