The gcc 4.6 version is compiled with frame pointer disabled, whereas the
4.4 version is compiled with frame pointers. Enabling the
-fomit-frame-pointer option with gcc 4.4 seems to cause issues as well.

Could you test passing -fno-omit-frame-pointers in the CFLAGS with gcc
4.6 to see if it avoids the issue?
