There are two asserts in this function. At the start,
g_assert(src);
and at the end...
g_assert(utf8_is_valid_string(dst));
The first means a problem higher. The second means a problem in this
function. Does "bt full" give more information? It should show the
parameters passed to the functions. Then it would be easy to see if
"src==NULL".
Do you have a PPC? I don't think that "char" and "unsigned char" have
problems like on an ARM. But anyways, I have some splint output
below, in case it is helpful to anyone...
Hth,
