multimedia/avidemux_qt4 has started dumping core with segfaults and other errors in libthread called from Qt4. I am suspicious that the real problem is in Qt4 and those errors were previously not detected and usually not causing a problem. The problem shows up with kernels at r320666 and later. The update on July 5 was: Add MAP_GUARD and use it for stack protection. Should I open a ticket for the Qt4 or should I spend more effort on whether it might be a kernel issue. (Pretty sure it's Qt4 at fault.) I might also look into updating the port to use Qr5 as Qt4 is clearly starting to bitrot and support for Qt5 has already been added upstream. -- Kevin Oberman, Part time kid herder and retired Network Engineer E-mail: rkoberman@gmail.com PGP Fingerprint: D03FB98AFA78E3B78C1694B318AB39EF1B055683
