[Freeciv-Dev] Problem using memprof

[Jan Dittberner <jan@xxxxxxxxxxxxxxxxx>]

Hello,

I tried to debug some memory leaks in freeciv (civclient PR#374)
with memprof 0.4.0, but it simply does nothing.
I do run, select /usr/local/bin/civclient, and then nothing
happens, I can select leaks, or profile, but there's no
action in memprof.

Also giving /usr/local/bin/civclient as command line parameter
doesn't help.

I use the HelixCode rpm of memprof-0.4.0 on Linux Mandrake 7.0
with glibc-2.1.3 and most recent gtk+ and gnome libraries.

I had the same problem with memprof-0.3.0.

I did an ltrace on "memprof /usr/local/bin/civclient" and there
where some interesting lines:

--------------------------------------------------------------
__xstat(3, "/usr/local/bin/civclient", 0x7ffff4d4) = 0
g_malloc(16, 0x080f5020, 0x080962d8, 776, 0)      = 0x080f4e98
g_hash_table_lookup(0x0810a6a0, 0x080f4e98, 16, 0x080f5020, 0x080962d8) = 0
g_hash_table_insert(0x0810a6a0, 0x080f4e98, 0x080f4e98, 0x080f5020, 0x080f5020)

--------------------------------------------------------------

I think running civclient fails starting, but don't know why.
Running civclient normally works by typing:

/usr/local/bin/civclient

in a terminal window.

Is this a known issue, can you give me hints how to examine
what's going wrong?
