glibc is actually able to report double-frees as double-frees directly, not just as generic heap corruption. He might have an older glibc though, which makes this less certain.
Yes, i'm using Sourcery G++ Lite 2008 Q3 version for arm-nonelinux-gnueabi 4.3.2.
The reason for I doesn't change to version 2010.09 4.5.1 is, if I use the newer compiler, my program will encounter an error on accessing eproms onboard while nothing difference in codes.
It's weird and I doesn't plan to check it right now.

Thanks、I used mtrace, but the result is still strange.
First, i'm sure my code is compiled with -g option.
but after analysis of my mtrace.log, it still reports "Caller" column as addresses ... such as 0x400366c4 etc, but not the code line.
btw, I tried another little program on fedora:
but after glibc detected "double free or corruption", the mtrace.log is still 0 bytes....nothing logged.
Why?
