[Bug c++/40705] New: Using -ggdb flag cause internal

[phorgan1 at gmail dot com]

The following code compiles cleanly without the -ggdb flag, i.e. using:

g++ -save-temps testit.cpp -o testit

but adding the -ggdb flag:

g++ -ggdb -save-temps testit.cpp -o testit

results in the following error output:

testit.cpp:10:1: internal compiler error: in gen_type_die_with_usage, at
dwarf2out.c:15108
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

Exact code compiled from testit.ii:

# 1 "testit.cpp"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "testit.cpp"
template <unsigned int n> class foo
{
public:
    typedef
 unsigned char type;
};

template<>
class foo<1>
{
    typedef enum {} type;
};

int
main()
{
}

Just noted that -ggdb is not required but merely -g
