free() panic

[Kwang-Keun Yi]

Hi, I think I need a help from you all genius unix hacker on my problem.
I got the following error message from malloc_debug() saying:

	"insert: bad block size (-120) at 0x0"

I tracked down the error is caused inside free().
In my program, I use a lot memory management library routines:
malloc(), calloc(), and free().  The problem is NOT because free() tries to
free non (m|c)allocated memory block. Free() definitely tries to free
a block allocated by calloc() before.
Do you have any insight or similar experience before?

I'll be much appreciative for your any helps. Thank you!
