Bugzilla Bug 181248

gdavl seems not to be 64bit ready. Compiled on amd64 I get this warnings:

gdavl.c: In function 'parse_tcnts':
gdavl.c:274: warning: comparison is always false due to limited range of data

Trying to run it results in a segfault. Compiled with -m32 there is only one
warning left:

gdavl.c: In function 'on_input':
gdavl.c:1759: warning: passing argument 4 of 'g_io_channel_read' from
incompatible pointer type

The resulting 32bit app works fine.

Reproducible: Always

I don't anything like gdavl in the official tree.

gdavl is part of sys-fs/davl which is in portage

He's right, i have the same problem.

This seems to be the SIGSEV cause:

in src/gdavl/if.c:52
    menu_items[i].callback_action = (guint)p;
 menu_items is a list of "GtkItemFactoryEntry" objects that declare the
callback field as "guint" == "unsigned int".
Unfortunately I don't know how to fix this.

The warnings seems to come from the use of ULONG_MAX which isn't the correct
size on != 32bit systems.

armin: Hope I didn't do anything wrong in adding you to CC.

I guess the keyword should be dropped, then.

Dropped keyword. armin76 says on IRC that this was never meant for amd64, so
*shrug*
