This is OK for mainline, provided that you add the testcase from the bugzilla PR to the dejagnu testsuite. Thanks.



Roger, thanks for review. I have added a testcase as requested.

The bug is still present on 3.4 branch. Is it OK to install the patch on the branch?

The 3.4 patch was bootstrapped on i686-pc-linux-gnu and regtested with c,c++ on 3.4 branch.

Uros.
