segfault in ratop

[Brian Candler]

I've just compiled argus 3.0.4 and argus-clients 3.0.4.1 under ubuntu 11.04
x86_64.

When I run ratop, it gives an immediate segfault. Here's the backtrace when
running under gdb:

Program received signal SIGSEGV, Segmentation fault.
fileno (fp=0x0) at fileno.c:37
37	fileno.c: No such file or directory.
	in fileno.c
(gdb) bt
#0  fileno (fp=0x0) at fileno.c:37

#3  0x000000000040a4d8 in ArgusClientInit ()
#4  0x0000000000415a8a in main ()
(gdb) 

This suggests a problem with curses, and indeed ratop -M nocurses doesn't
crash (although I don't see it outputting anything useful either)

The following curses-related packages are installed on my system:

$ dpkg-query -l | grep -i curses
ii  lib32ncurses5                                   5.7+20101128-1                               shared libraries for terminal handling (32-bit)

And ratop linkage:

	libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f65f9a35000)

Any suggestions for how I can pin down the problem?

Thanks,
