Hi kevin,

Thanks to pointing this out. From gcc 4.6.2 manual:

"Starting with GCC version 4.6, the default setting (when not
optimizing for size) for 32-bit Linux x86 and 32-bit Darwin x86
targets has been changed to -fomit-frame-pointer. The default can be
reverted to -fno-omit-frame-pointer by configuring GCC with the
--enable-frame-pointer configure option."

I am out of office now. Tomorrow I will test compiling with
-fno-omit-frame-pointer. Thanks again.
