If the GC is running you get a stack trace with fullcollect() like this:

cache-d_d.exe!gc at gc@Gcx at mark(void * this, void * nRecurse, int ptop) 
Line 2266    C++
      cache-d_d.exe!gc at gc@Gcx at mark(void * this, void * ptop) Line 2249 
   C++
      cache-d_d.exe!gc at gc@Gcx at fullcollect() Line 2454    C++
      cache-d_d.exe!gc at gc@GC at mallocNoSync(unsigned int this, unsigned 
int alloc_size, unsigned int * alloc_size) Line 458    C++
      cache-d_d.exe!gc at gc@GC at malloc(unsigned int this, unsigned int 
alloc_size, unsigned int * bits) Line 413    C++
