That's the only place that routine is called... which may be why nobody else
has it the problem. However, I can't make it fail - I'm running something
like the 18th - but the code in emitter hasn't changed since 2/4
(myGlobals).
Looks like an attempt to free unmalloced memory... or double free it...
Anyway - try this... @ the end of emitter.c, the code:
if(filterPattern.fastmap)
free(filterPattern.fastmap);
s/b
if(filterPattern.fastmap != NULL)
free(filterPattern.fastmap);
Also, there is another case around line 687... should probably get the same
treatment.
Pls let me know!

Subject: [Ntop] Mutex.C Segmentation Fault
Hi All,
NTOP (02/15/2001) violently dies when I try to use ./protoUsage.pl. I'm
running NTOP on Athlon 1700 with 512Mb RAM (220 free during this incident)
and RH 7.2 (no patches, gcc-2.96-98, glibc-2.2.4-13). I'd appreciate any
insight on this issue. This is also happening when trying to do this
manually http://ntophost:port/dumpTrafficData.html. I get the dump and then
NTOP dies.
Here is the debug from my machine:
Program received signal SIGSEGV, Segmentation fault.

Any thoughts on this issue are appreciated.
