Thread: Segmentation fault in psql

I'm getting a segmentation fault in psql in 7.3.2.  Last working version I
had was 7.2.4.  Here's the backtrace from the debugger.

> Program received signal SIGSEGV, Segmentation fault.

I'm getting an invalid address back everytime pg_encoding_to_char is called.
I added a printf to the function (shown below) and then everything works
fine.  I think it has something to do with the optimizations but I don't
know where to change that.

const char *
pg_encoding_to_char(int encoding)
{
        if (PG_VALID_ENCODING(encoding))
        {
                pg_enc2name *p = &pg_enc2name_tbl[encoding];

                Assert(encoding == p->encoding);
                printf("p->name = %s\n",p->name);
                return p->name;
        }
        return "";
}
