I managed to get it working by hard-coding the offset (ugh!):
syscall::lstat64:return
/ self->stat && pid == $target /
{
this->path = copyinstr(self->path);
printf("Path: %s\n", this->path);
this->stat = copyin( self->stat + 0x34, sizeof(long long) );
printf("File size: %lld\n", *((long long *)(this->stat)));
self->stat = 0;
}
