Energia - Assembler warning

I'm using a FR5969 board (Rev 2) with Energia version 14 on a Mac running OS X 10.10.1. My sketch uses a 32767 byte block of the device's 'ROM' for storage and in total the memory used is given as 46667 bytes of 65536.

So the initial part of my code includes:

#define PERSIST __attribute__((section(".text")))

The program seems to run correctly except that I'm concerned about a warning:

'Assembler messages: C:\Documen~1\TBA\LOCAL~1\Temp\\ccAA9W6Q.s:1758:Warning: ignoring changed section attributes for .text

(Actually, it produces the same error on Windows XP.)

What I'd like to know is what is this error and if it's safe to ignore (must be incredibly doubtful).

TIA

Steve
