Specify the minimum size
of a block for stack trace
collection. GDB report
leaks of blocks, smaller
than this value. However,
no stack trace is provided.

min_leak_size = <num> (or)
set heap-check min-leak-size
<num>
Specify the depth of call
stack to be captured
set heap-check
frame-count <num>
frame_count = <num> (or) set
heap-check frame-count <num>
Instruct GDB to stop,
whenever a block at the
given address gets allocated
or deallocated.

tions of malloc.

null after <num> bytes have
been allocated by malloc.
