README for Memory Allocation Debugging
|
||
|
|
|
||
|
|
If it is necessary or desired to debug the memory allocation
|
||
|
|
process in LZMA, edit the file C/Alloc.c and uncomment the
|
||
|
|
line:
|
||
|
|
|
||
|
|
/* #define _SZ_ALLOC_DEBUG */
|
||
|
|
|
||
|
|
Then, add this to the Makefile and relink. This output will
|
||
|
|
show chunks of memory Alloc uses during LZMA compression.
|
||
|
|
|
||
|
|
Output will appear similar to this:
|
||
|
|
|
||
|
|
Alloc 284484 bytes, count = 0, addr = 44251008
|
||
|
|
Alloc 65536 bytes, count = 1, addr = 80636F0
|
||
|
|
Alloc 12288 bytes, count = 2, addr = 80736F8
|
||
|
|
Alloc 12288 bytes, count = 3, addr = 8076700
|
||
|
|
Alloc 4456448 bytes, count = 4, addr = 43E10008
|
||
|
|
Alloc 102877690 bytes, count = 5, addr = 3DBF3008
|
||
|
|
Alloc 604246024 bytes, count = 6, addr = 19BB1008
|
||
|
|
Free; count = 6, addr = 43E10008
|
||
|
|
Free; count = 5, addr = 19BB1008
|
||
|
|
Free; count = 4, addr = 3DBF3008
|
||
|
|
Free; count = 3, addr = 80736F8
|
||
|
|
Free; count = 2, addr = 8076700
|
||
|
|
Free; count = 1, addr = 80636F0
|
||
|
|
Free; count = 0, addr = 44251008
|
||
|
|
|
||
|
|
As you can see, LZMA takes large chunks of ram and sometimes
|
||
|
|
it can use more than what is available and return an
|
||
|
|
SZ_ERROR_MEM (2) code.
