This GDB was configured as "sparc-sun-solaris2.6"...partial-stab.h:441: gdb-internal-error: sect_index_data not initialized

An internal GDB error was detected. ...

if I change the bad.c source file, to create an initialized
global variable (and hence creating a .data section),
no error.

problem does not appear to occur with version 5.0, but does
with 5.1 and 5.2

to workaround, add an initialized global variable to the
file so that there is a .data section.
>How-To-Repeat:
create a simple bad.c file with no .data section, and 
at least one global variable. then
compile with "gcc -g -c bad.c"

for example:

int junk;
foo(){junk++;}

then execute gdb bad.o
