[Bf-committers] request for win32 debugger

outliner.c, line 443 see below.
str is uninitialized memory because when outliner
calls get_constraint_target, con is type 0, flag is
17, and name is "Const". get_constraint_target does
not recognize type 0, and so str never gets
initialized. Therefore the code crashes.
The routine get_constraint_target does not have a
default: case to set the str pointer to 0.
This does not fail on Linux because the behavior of
malloc is different. WHen a linux app starts, the
memory is cleared to zero. On Windows this does not
happen.
You must insert
*subtarget= NULL;
just before get_constraint_target's return NULL
statement at the end of the function at line 386 of
constraint.c.
I hope someone can patch this fix into CVS,
Thanks
if(ob!=G.obedit) { // channels undefined in
editmode, but we want the 'tenla' pose icon itself
int a= 0;
for(pchan= ob->pose->chanbase.first; pchan;
pchan= pchan->next, a++) {
ten= outliner_add_element(soops,
&tenla->subtree, ob, tenla, TSE_POSE_CHANNEL, a);
ten->name= pchan->name;
ten->directdata= pchan;
pchan->prev= (bPoseChannel *)ten;
if(pchan->constraints.first) {
Object *target;
bConstraint *con;
TreeElement *ten1;
TreeElement *tenla1=
outliner_add_element(soops, &ten->subtree, ob, ten,
TSE_CONSTRAINT_BASE, 0);
int a= 0;
char *str;
tenla1->name= "Constraints";
for(con= pchan->constraints.first; con; con=
con->next, a++) {
ten1= outliner_add_element(soops,
&tenla1->subtree, ob, tenla1, TSE_CONSTRAINT, a);
target= get_constraint_target(con, &str);
if(str && str[0]) ten1->name= str;
