Query on malloc

[Venkata Rajesh Velamakanni]

Hello All,   This is regarding a query on malloc. Can any one tell me from where I can get the source code of malloc.c I observed that malloc / calloc is giving Sigmentation fault. I would like to know the situations in which this can happen. Can any one help me by going through the following traces from gdb.     Following are the back traces from gdb: --------------------------------------------   Breakpoint 2, H245_InternalClose (H245SessionPtr=0x8053fc0)     at h245Common.c:3342 3342      ptr = malloc(len); (gdb) n   Program received signal SIGSEGV, Segmentation fault. 0x4015c4e1 in chunk_alloc (ar_ptr=0x401f1040, nb=16) at malloc.c:2699 2699    malloc.c: No such file or directory.
