>Description:
Running ipmon -F from Darren Reed's ipfilter V3.2beta3 causes a core dump:
8000 bytes flushed from log buffer
[....] pid 191 (ipmon) uid 0: exited on signal 11 (core dumped)
Segmentation fault (core dumped)
Recompiling ipmon with the -g option and running it under gdb gives
0x8061e3a in vfprintf ()
when processing line 602 in ipmon.c:
fprintf(log, "%d bytes flushed from log buffer", flushed);
If I replace line 602 by
printf("%d\n", flushed);
there is any problem.
Some more informations:
whatis flushed: type = int
print flushed: $1 = 8160
Processor: AMD K5-P133
