Hi Percy, your segfault does not instantly ring a bell with me, but before you/we dive deeply into this, I am wondering whether you could upgrade from you Oct2012-SP2 to Oct2012-SP3 or even Feb2013, and check whether the crash(es) still occur? Stefan ----- Original Message -----
Dear Monet Team,
We're having an issue in which certain data is causing mserver5 to crash. After this condition is hit, mserver5 crashes at every startup and always dumps an identical core.
We're running Monet 11.13.7 on Ubuntu Linux 64 bit.
The error is happening on line 1142 of gdk_atoms.c:
if (GDK_STRCMP(v, (str) (next + 1) + extralen) == 0) {
Examining the core dump revealed that (next + 1) + extralen is referring to an out of bounds address. Here's the backtrace:
