--- Comment #5 from Ramana Radhakrishnan ramana at gcc dot gnu.org ---
(In reply to Ramana Radhakrishnan from comment #4)
I am seeing the same with a cross compiler configured with
$SRCDIR/configure --target=arm-none-linux-gnueabi --with-arch=armv7-a
--with-fpu=vfpv3-d16 --with-float=softfp --enable-checking=release and a
number of other unrelated flags in a gdbserver build.
Will attach the testcase as I have it and a reduced one in a few minutes.
reduced testcase looks very similar to what's here but here goes.
extern struct _IO_FILE *stderr;
struct __jmp_buf_tag
{
};
typedef struct __jmp_buf_tag jmp_buf[1];
extern jmp_buf toplevel;
int
main (int argc, char *argv[])
{
int bad_attach;
int pid;
char *arg_end, *port;
char **next_arg = argv[1];
volatile int attach = 0;
if (_setjmp (toplevel))
{
}
next_arg++;
{
gdbserver_usage (stderr);
}
{
next_arg++;
}
if (attach
(*next_arg == ((void *)0)
|| (pid = strtoul (*next_arg, arg_end, 0)) == 0
|| next_arg[1] != ((void *)0)))
bad_attach = 1;
}
