Hi,
after a couple of regular updates of openSuSE 12.3 starting in August 2013 I noticed today that a software that I succesfully compiled and executed in August does not run anymore, when it is executed by an ordinary user. However, it successfully executes when it is run as root!
Compiler = gcc (SUSE Linux) 4.7.2 20130108 [gcc-4_7-branch revision 195012]
Here are the error messages I get, when I execute the software “funccalc” as an ordinary user:
*** Error in `funccalc’: free(): invalid next size (fast): 0x00000000006faa00 ***

Abort
The error seems to be triggered when a ncurses window is deleted per “delwin”.
I suspect a bug in one of the recent updates to have caused the problem.
Does anyone have a better idea?
Thanks
