I tried busybox 1.20.0 with gcc 4.6.1 without -fno-asynchronous-unwind-tables
tc@box:~/busybox-1.20.0$ make defconfig
tc@box:~/busybox-1.20.0$ make
tc@box:~/busybox-1.20.0$ size -A busybox | grep eh_frame
.eh_frame_hdr 44 135260064
.eh_frame 200 135260108
tc@box:~/busybox-1.20.0$ size -A busybox_unstripped | grep eh_frame
.eh_frame_hdr 44 135260064
.eh_frame 200 135260108
I don't get a huge .eh_frame section here... Is it produced by some custom configuration?
