Thanks Andreas for the tip, I didn't think of checking the distro patches.

I was able to reproduce with this:

$ cat allo.c
int salut;
$ gcc allo.c -fPIC -o allo.o -g3 -O0 -c
$ gcc allo.o -shared -nostdlib -nodefaultlibs -o allo.so
$ ./gdb -q -nx a.out
Reading symbols from a.out...
(gdb) start
Temporary breakpoint 1 at 0x1136: file test.c, line 1.
Starting program: /home/smarchi/build/binutils-gdb/gdb/a.out
/home/smarchi/src/binutils-gdb/gdb/objfiles.h:524: internal-error: sect_index_text not initialized
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
