You didn't mention which version of gcc you are testing. With current
gcc see if the -fvar-tracking option helps.

Thanks for your time and help. I'm currently using two versions of GCC
under Windows. (MinGW GCC 4.4.4 and MinGW GCC 4.5).
The gdb I built was (gdb cvs 20100613 and gdb cvs 20100618, both with
python support), but both of the gdb will get crash when I run the "info
locals" command.
I'm not sure I have catch the core idea about my question, because I
found an old post here:
http://gcc.gnu.org/ml/gcc/2007-04/msg00138.html ,there, you suggest add
the DW_AT_start_scope somewhere.
As you said, if I add the "-fvar-tracking" option, there will have debug
information included. Then, GDB can use this information to avoid to
print the uninitialized local variables?
Thanks.
