I'm now able to reproduce this problem by using an older gcc version (3.2 vs. 3.3) and no optimization flag enabled. The bug is related to how values are being stored and updated into the global variable "Astro astro" after consecutive calls. Just to demonstrate the problem, here is the bad results of the attached testcase:
5:25 6:39 12:57 16:30 19:15 20:30 --- 5:25 20:54 12:57 16:30 6:35 20:30 --- This problem is now fixed on CVS. It would be great if you can confirm this by downloading the updated files available right here: http://cvs.arabeyes.org/viewcvs/projects/itl/libs/prayertime/src/ Although we should probably not make a habit of it, but if this bug is confirmed as fixed, I think it is a major enough problem (for GUI apps) to deserve an 0.6.2 release.
