Subject:Re: failing row[] assignment
View as plain text  
If the examples run without issue, I would start by going over your own code
first. What's the type for temp->state?

Is it a pointer or a std::string? If it's a string, what happens if
you get rid of the cast to (const char *) on the assignment?
