Hi, i hope i'm not wrong, but:
Gorgo:~# cat p.c
int main(void)
{
return (0);
}
Gorgo:~# gcc -Ttext=0x0 p.c -o p
Gorgo:~# ./p
p[3013]: segfault at fffff034 ip b7ee9086 sp bf804368 error 4 in ld-2.9.so[b7ee7000+1c000]
Segmentation fault
Gorgo:~# diet -v gcc -Ttext=0x0 p.c -o p
gcc -nostdlib -static -L/usr/lib/diet/lib-i386 /usr/lib/diet/lib-i386/start.o -Ttext=0x0 p.c -o p -
isystem /usr/lib/diet/include -D__dietlibc__ /usr/lib/diet/lib-i386/libc.a -lgcc
Gorgo:~# ./p
Gorgo:~#
Same with .data section and if i compile static with simple gcc too. Beyond 0x100 i have a link error:
/usr/bin/ld: p: Not enough room for program headers, try linking with -N
/usr/bin/ld: final link failed: Bad value
collect2: ld returned 1 exit status
The system is a Debian/testing.
Regards
Pierre

Then don't do this. You cannot just change the way linking works and expect it
to work.

Ok, but why doesn't it says that it's an invalid value as it does for
0x100?

That would be a bug in binutils.
