I've noticed the same behavior as henkpoley, the debug build runs just fine, 
where as otherwise I get an Abort 
Trap.  1.01b

Can you run it under gdb, and then give me the output of the 'back' command 
when it
aborts?

I *believe* this may be fixed by:
http://skipfish.googlecode.com/files/skipfish-1.03b.tgz

Please let me know.

Hi, I'm seeing the same issue with 1.03b.  I've attached the gdb output (I 
think I did this 
correctly, let me know if you need more info).

Looks like my gdb output didn't get attached.  Here is the output:

I have the exact same problem with OS X 10.6.2, libidn 1.18, skipfish 1.03b. 
The backtrace looks the same as 
well.

This looks exactly like a problem that should be fixed by now (a glitch in
FORTIFY_SOURCE). I have two more suggestions; please let me know if this makes 
any
difference:

1) Edit Makefile, find this line:

CFLAGS_GEN = -Wall -funsigned-char -g -ggdb -U_FORTIFY_SOURCE

...and replace it with:

CFLAGS_GEN = -Wall -funsigned-char -g -ggdb -DFORTIFY_SOURCE=0

Then try 'make clean all'. Let me know if anything changes.

2) Replace the same line with:

CFLAGS_GEN = -Wall -funsigned-char -g -ggdb -D_FORTIFY_SOURCE=0

...and likewise, 'make clean all'.

If all this fails, using the scanner with 'make clean debug' and redirecting 
stderr
to a file (2>logfile.txt) is the best short-term option; and I will investigate 
a bit
more.

The first change had the same issue. The second one fixed the problem.

Thanks!
