The following C++ generates an ICE with today's trunk when -g is passed:
extern int strlen (const char *__s) throw();
namespace std {
using ::strlen;
}
void foo()
{
using std::strlen;
}
jan@cliff$ g++ -g -c t.cpp
t.cpp: In function ?void foo()?:
t.cpp:9: internal compiler error: tree check: expected class ?declaration?,
have ?exceptional? (@@dummy) in lookup_decl_die, at dwarf2out.c:5415
Obviously, this is a reduction of a usual pattern,
#include <cstring>
void foo()
{
using std::strlen;
}
The same result is obtained when strlen is replaced by another libc-function
like printf. If 'strlen' is replaced by anything else (like 'bar', say),
everything is fine.
