Some glibc, like the one in Fedora 9, will check invalid pointers passed to
free by default.  If you use Linux, you can try

[hjl@gnu-26 binutils]$ MALLOC_CHECK_=1 ./addr2line -e ./addr2line `nm
-n  --defined-only  ./addr2line |head -1 | awk '{print $1}'`
malloc: using debugging hooks
??:0
*** glibc detected *** free(): invalid pointer: 0x0000002a95734d53 ***
[hjl@gnu-26 binutils]$
