Description:
isam/test3.c has the same one-byte buffer overrun previously reported in myisam/mi_test3.c (bug #6782) and needs the same fix.  Hadn't noticed this at the time because we weren't building the isam code ...

How to repeat:
examine code: 11 bytes do not fit in a 10-byte buffer

Suggested fix:
The patch used for myisam was

-  strmov(record.text,"Testing...");
+  strnmov(record.text,"Testing...", sizeof(record.text));
