info leaks filename Writes the complete leak report output to the
specified file.
info leak leaknumber Produces detailed information on the specified
leak including the allocation call stack.
set heap-check block-size
num-bytes
Instructs WDB to stop the program whenever it
tries to allocate a block larger than num-bytes in
size.
set heap-check heap-size
num-size
Instructs WDB to stop the program whenever it
tries to increase the program heap by at least
num-bytes.
min-heap-size This option reports the heap allocations that
exceed the specified number of bytes
based on the cumulative number of bytes that
are allocated at each call-site, which is inclusive
of multiple calls to malloc at a particular call
site.
set heap-check watch
address
Stops the program whenever a block at a
specified address is allocated or deal- located.
set heap-check null-check
[N | random]
Force malloc to return NULL after N or random
number of invocations of malloc. Use set
heap-check random-range N
and set
heap-check seed-value N to define the seed
value and range for random number calculation.
Useful for simulating out-of-memory situations.
set heap-check
null-check-size N
Force malloc to return NULL after N bytes have
been allocated by the program.
catch nomem Allows the user to get control of an
out-of-memory event. The user can step through
once the nomem event is caught to see whether
the out-of-memory event is handled correctly.
set heap-check free [on |
off]
When set to on, forces WDB to stop the program
when it detects a call to free() with an
improper argument, a call to realloc() that
does not point to a valid currently allocated heap
block, or a call to free a block of memory, which
has been corrupted. Refer set heap-check
bounds
for details on detecting memory
corruption.
set heap-check string [on
| off]
Toggles validation of calls to strcpy, strncpy,
memcpy
, memccpy, memset, memmove, bzero,
