xxdiff test suite
Description of problem: xxdiff appears to have performance issues when using the Qt libraries from RHEL 7.6 (as opposed to 7.4).
Version-Release number of selected component (if applicable):
How reproducible: Consistently.
Steps to Reproduce:
Download the attached test package and follow the instructions in the README.
Actual results: xxdiff slows down by an order of magnitude when linked against the Qt 4.8.7 libraries.
Expected results: xxdiff shows no performance slowdown when linked against the Qt 4.8.7 libraries.
The libraries that came with the test package are the Qt 4.8.5 libraries that were shipped with RHEL 7.4, so it seems there's a performance regression.
Using the reproducer is #c7, qt-4.8.7-3.el7 takes a few seconds and qt-4.8.7-2.el7 takes well over a minute to complete, verified.
