Suppose foo.cpp contains this:
void foo() {
static struct {
struct {
virtual void func() {}
} test1;
} test2;
}
If you compile this with gcc-3.4.2 and invoke gdb:
g++ -g -c foo.cpp && gdb foo.o
gdb dies with:
/gdb/dwarf2read.c:5000: internal-error: could not find partial DIE in cache
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Honestly, I don't know if this is a bug in gcc or gdb, but I don't know how to
find out. Whichever it is, I bet there's something fishy about the name of a
vtable for a nested function-local class.
