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.
