malloc: fix compile error
Commit Message
Since e9c4fe93b3855239752819303ca377dff0ed0553, the commit changes struct
malloc_chunk member "size" to "mchunk_size". This cause a compile error
in function dump_heap, if macros MALLOC_DEBUG has defined and the value is
larger 1.
producing the following error message:
In file included from malloc.c:1884:0:
arena.c: In function ‘dump_heap’:
arena.c:422:58: error: ‘struct malloc_chunk’ has no member named ‘size’
fprintf (stderr, "chunk %p size %10lx", p, (long) p->size);
^~
arena.c:428:17: error: ‘struct malloc_chunk’ has no member named ‘size’
else if (p->size == (0 | PREV_INUSE))
