Segmentation fault at malloc.c:4232

hi,

I have written a program and it failed with "Segmentation fault". With
gdb, it seems that there is something wrong in the malloc.c:

gdb) set args src.txt
(gdb) r
Starting program: /home/hpt/test/c/algorithms_in_c/4.17/compiler src.txt

Program received signal SIGSEGV, Segmentation fault.
_int_malloc (av=0x996120, bytes=14) at malloc.c:4232
4232          bck->fd = unsorted_chunks(av);
(gdb) where
#0  _int_malloc (av=0x996120, bytes=14) at malloc.c:4232

#3  0x08048565 in main (argc=1, argv=0x0) at compiler.c:16

Is this a bug?
