compiler error with gcc 4.9

I have tested some copilers for chdk-de buildserver.

gcc 4.8.3 and gcc 4.8.4 works fine, but gcc 4.9.2 (also launchpad gcc-arm-none-eabi-4.9, see attachment) breaks on buildig curves.flt.
Have anyone an idea?

srsa_4c DIGIC 6 trunk was build successfully with all tested compilers on linux 64bit.

The compiler is creating an extra .rodata segment (.rodata.cst2) which the elf2flt program is not expecting.

I'll see how easy it will be to fix, in the meantime don't use 4.9.2.

Edit: I've updated the linker script so it should now work for all compiler versions (revision 3902).

Phil.
