BUG?: .lcomm and #define is not working with xassembler-with-cpp

BUG?: .lcomm and #define is not working with xassembler-with-cpp

[Klaus Rudolph]

Hi all,

if I have the folowing code lines:
#define CONST1 100

.lcomm VAR1 CONST1
.lcomm VAR2 2*CONST1
.lcomm VAR3 (1+CONST1)*2

the last line will run into an error:
check.s: Assembler messages:
check.s:5: Error: missing size expression

I tested with target avr and i386, some result.

in binutils-2.14 the code works, it is broken since 2.15, also in snapshot
041223.

The gcc is in good and fail case gcc-3.4.3. Seems only dependend on 
binutils.

Is a workaround available?

Bye
   Klaus

I tried this using the following (postprocessed) test case:

  .lcomm VAR1 100
  .lcomm VAR2 2*100
  .lcomm VAR3 (1+100)*2

and it worked:

bje@namadgi:~/build/binuitls/gas$ ./as-new ~/foo.S -o foo.o
bje@namadgi:~/build/binuitls/gas$ ./as-new --version

Are you sure this applies to i386?
