Build Identifier:

Assertion failure in gdk_bat.c

Reproducible: Always

Steps to Reproduce:

  1. start mserver5 (MonetDB 5 server v11.17.21 "Jan2014-SP3")
  2. start mclient
  3. execute SQL commands:
    CREATE TABLE FLOAT8_TBL(f1 double);
    INSERT INTO FLOAT8_TBL(f1) VALUES (' -34.84');
    select sign(f1) as sign_f1 from float8_tbl f;
    INSERT INTO FLOAT8_TBL(f1) VALUES ('1.2345678901234e+200');
    select sign(f1) as sign_f1 from float8_tbl f;

Actual Results:
