segfault at chunk_alloc() / malloc() |

My program somtimes crashed at chunk_alloc().
malloc() is called more than 10M times at that time.
I'm using glibc-2.2.5-34.rpm (from redhat 7.3)
#0 chunk_alloc (ar_ptr=0x401b8fa0, nb=16) at malloc.c:2877
2877: victim_size = chunksize(victim);
(gdb) p *victim
Cannot access memory at address 0xc000100
#1 0x40105058 in __libc_malloc (bytes=8) at malloc.c:2811
Occasionally it is crashed at malloc.c:2894
2894: victim_size = chunksize(victim);
(gdb) p *victim
Cannot access memory at address 0x20
