[Bug c/36516] New: Gcc fails on huge C source files.

["alexey dot zaytsev at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Gcc 4.3 crashes on the 38 megabyte file generated with:

#!/usr/bin/perl -w

print <<EOF;
struct a {
        int i;
        char c;
};
EOF

for ($i = 1; $i < 1000000; $i++) {
        printf "struct a a_%d = {\n", $i;
        printf "        .i = $i,\n";
        printf "};\n\n";
}

The test was run as 

./gcc-test.pl > test.c
gcc-4.3 -c test.c

Gcc-4.2 was able to handle a file 4 time bigger (4M entries),
eating only about 2 gigabytes or RAM. I was not able to confirm
that it could survive 6M, because ot the limited ram and
trashing swap. Was comfirmed to work wint at least 10M by others.
The tests were run on Debian-patched gcc, but were confirmed with
vanilla gcc by others.
