Date: Thu, 30 Jun 2022 12:35:13 +0000 [thread overview]
Message-ID: <bug-29294-4717-09BAkbYRNV@http.sourceware.org/bugzilla/> (raw)

--- Comment #7 from Tom de Vries <vries at gcc dot gnu.org> ---
Reproduced:
...
$ cat test.cc
struct Base { const char *Bar; };
struct Foo : public Base
{
static const int m_MsgIdx = 0;
};
static void
Func (const char* Foo::*Field)
{
}
int
main ()
{
Func (&Foo::Bar);
}
$ g++ -g test.cc
$ gdb -q -batch a.out -ex start -ex step
Temporary breakpoint 1 at 0x4004d6: file test.cc, line 16.
Temporary breakpoint 1, main () at test.cc:16
16 Func (&Foo::Bar);
Func (Field=/home/vries/gdb_versions/devel/src/gdb/gdbtypes.h:695:
internal-error: loc_bitpos: Assertion `m_loc_kind == FIELD_LOC_KIND_BITPOS'
failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
