[committed] testsuite: Add testcase for already fixed PR [PR109925]

[Jakub Jelinek]

Hi!

This testcase was made latent by r14-4089 and got fixed both
on the trunk and 13 branch with PR113372 fix.

Adding testcase to the testsuite and will close the PR as a dup.

Bootstrapped/regtested on x86_64-linux and i686-linux, committed to trunk as
obvious.
