Bug#224200: gcc-3.3 fails to generate EH_FRAME program-header

[David Mosberger <davidm@hpl.hp.com>]

Package: gcc-3.3
Version: 1:3.3.3-0pre0
Severity: important
Tags: sid

It appears that the behavior of Debian gcc-3.3 is inconsistent with
that of Red Hat's gcc-3.2 when -fexceptions is specified.  Example:

On Debian/testing:

 $ cat t.c
 int main (int argc, char **argv) {
        printf ("hello\n");
 }
 $ gcc-3.3 -fexceptions t.c
 $ objdump --priv a.out |grep EH
 (no output)

On Red Hat 9:

 $ cat t.c
 int main (int argc, char **argv) {
        printf ("hello\n");
 }
 $ gcc -fexceptions t.c
 $ objdump --priv a.out |grep EH
 EH_FRAME off    0x00000420 vaddr 0x08048420 paddr 0x08048420 align 2**2

I believe this is a serious problem because it means that a DWARF2
unwinder will not be able to unwind across C code even though it was
compiled with -fexceptions.
