Summary: memory pattern question

Initial Comment:
Hi, 

My team developed an application in C++. The application's working set increases steadily. All leaks we could track we corrected. The last remaining leak is a difficult one. The reason I post this message here is to see if someone has an idea of what this data structure could be or a pointer to where I could look. We use template stuff in the code (trees, sets, etc etc). We look at the memory by hexanalyzing a forced core. (this is a linux app). The pattern is inside blocks of malloce'd space and these blocks appear larger and larger with similar content. The patter is as follows:

int
char [4]
void *;
void *

Exactly 16 bytes, the int is 1 or 2 for the most part but I have seen 0xFFFFFFFF at times. The char at times has character but never no more than 3 followed by \0. The last two seem to be real pointers and at time 0x20 and 0x40 from each other. 

At first glance it looks like a tree entry but not sure. 

Any ideas ?
Thanks
David De La Rosa
