When I use the -fdata-sections option, the compiler crashes
whenever it sees a global initialized variable. Any ideas on
how to fix this?

$ cat foo.c

static unsigned u = 1;

unsigned foo(void)
{
return u;
}

$ msp430-gcc -mmcu=msp430x4250 -g -Wall -W -Wpointer-arith -Wcast-align -Wshadow -Wundef -Wwrite-strings -O1 -fomit-frame-pointer -fshort-double -DENABLE_DIAG_PRINTF=1 -fno-builtin-memcpy -fno-builtin-memset -DExternalReference=1 -DHasTempSensor=1 -ffunction-sections -fdata-sections -c foo.c
foo.c:2: Internal compiler error in unique_section, at config/msp430/msp430.c:1972

In my case, if I add -fdata-sections I end up with [assembler] errors:

/var/tmp//ccCmGzjA.s: Assembler messages:
/var/tmp//ccCmGzjA.s:724: Error: unrecognized symbol type ""
/var/tmp//ccCmGzjA.s:724: Error: junk at end of line, first
unrecognized charact
er is `0'

We're running different versions of mspgcc (mine is 3.4.4, see my post
from the other thread).

It looks like -fdata-sections is pretty much broken. :/
