Binary compiled with GCC-4.7.2 has a different epilogue/prologue sequence when compared with the same binary emitted by GCC-3.3.6. I'm sure I haven't used fomit-frame-pointer compilation flag. What could be the issue here ? Is the linker doing some optimization here ? It has rendered my executable undebuggable in gdb.
