[Bug c/21567] New: Segmentation fault of the compiler when compiling

[alexander_herrmann at yahoo dot com dot au]

The compiler get's a segmentation fault on this one :)
The compiler 4.0.0 was configurated with  --enable-languages=c,c++,java
--enable-shared --enable-threads=posix --with-cpu=i686 and built with make
CFLAGS='-O' LIBCFLAGS='-g -O2' \
            LIBCXXFLAGS='-g -O2 -fno-implicit-templates' profiledbootstrap

The original error message reads:

bug.c: In function 'aie_sql_meta_create_index':
bug.c:25: warning: 'tableid' is used uninitialized in this function
bug.c: In function 'main':
bug.c:25: warning: 'tableid' is used uninitialized in this function

So this bug is a dupe of PR 21364.
