I've now got a collection of valgrind logs from libsepol from git revision 5447c8490b318ef64c61eb6022baddca69233733 (latest as of yesterday afternoon). I presume that the valgrind logs of "Conditional jump or move depends on uninitialised value(s)" corresponds to a SEGV when not running valgrind but haven't proven that yet. I have not yet worked out how to reproduce the bug on another system. Nickolas, thanks for all your suggestions I will go back to them once I have more test results. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
