  • umonitor: Segmentation fault (core dumped)

    From Rampage@VERT/SESTAR to digital man on Sun Mar 15 11:03:42 2020
    i'm trying to view my sbbsecho.log file from umonitor...

    i've looked and adjusted things but still cannot get a core file to analyze... i've also apparently not done a proper job of pointing gdb to the source files but i have done the best i can running umonitor in gdb to get the following...


    /sbbs/data$ ls -la sbbsecho.log
    -rw------- 1 sbbs sbbs 15127005 Mar 15 10:43 sbbsecho.log


    blank lines added to the following to avoid word wrap muck...

    i'm guessing the problem is the size of my sbbsecho.log but this could be handled more gracefully, i think...

    Yes, it was allocating the memory for the call stack and 15MB is really too big for most stacks. I just committed a change to allocate that memory from the heap instead. Give that a shot.

    no doubt, eh? :)

    it seems to work now... thanks :)
