Summary: corrupted values after multiple INSERT/DELETEs

Initial Comment:
The attached SQL statements lead to wrong output on MonetDB-SQL Feb2010. The 
final SELECT statement should result in the string 'modified' in the column 
"value", but it doesn't. Most likely it is a memory-related bug as most of the 
time, I get an empty string there, but during isolation of a reasonably small 
test case, I also got arbitrary binary data, and on occasion a string length 
overflow assertion breaking inside str.mx.

The test system runs CentOS 5.4 on x86_64, having MonetDB compiled with 64-bit 
OIDs. The compiler was "gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-46)".
