Error from EEPROM library while compiling

[gofaster]

EDIT: Please ignore the below. The build failure was caused by something else.

-- original post ---
I am using the EEPROM library in a project. It was compiling fine with Teensyduino 1.29-beta2 (I think that was the version I had prior to updating to the release version a few days ago). Today I deleted the temporary build directory to force a complete rebuild and am getting the following compile error.

The following is the code fragment that's been compiling fine for weeks until now

int32_t adc_0_offset = 0, adc_1_offset = 0 ; // offset correction.  Retrieve values from EEPROM
float adc_0_gain = 0.0, adc_1_gain = 0.0 ; // factor correction.  Retrieve values from EEPROM

// save to EEPROM.
      eepromAddress = 0;
      calExists = 88;  // flag that calibration values exist in EEPROM
      EEPROM.put(eepromAddress, adc_0_gain);
      eepromAddress = eepromAddress + sizeof(float);
      EEPROM.put(eepromAddress, adc_0_offset);
      eepromAddress = eepromAddress + sizeof(int32_t);
      EEPROM.put(eepromAddress, adc_1_gain);
      eepromAddress = eepromAddress + sizeof(float);
      EEPROM.put(eepromAddress, adc_1_offset);
      eepromAddress = eepromAddress + sizeof(int32_t);
      EEPROM.put(eepromAddress, calExists);

What have I done wrong?
