I have looked further at the bug I reported to you earlier today (with
g++ 1.34.0 on the SPARC). It turns out to be a problem with ld++
If you compile and run the following, you'll see the problem.

static double x;

main()
{
  x = 1.0;
}

What happens is that the bss segment ends up being aligned
on a 4-byte boundary, which causes the program to generate
a bus error on execution.

The following diff seems to fix this problem:

*** ld.c.distrib	Sat Feb 25 21:41:56 1989
--- ld.c	Sun Mar 12 11:37:27 1989
***************
*** 2189,2194 ****
--- 2189,2195 ----
    outheader.a_text += N_ADDRADJ (outheader);
  #endif
  
+   data_size = (data_size + sizeof(double) - 1) & ~(sizeof(double)-1);
    /* Make the data segment address start in memory on a suitable boundary.  */
  
    data_start = N_DATADDR (outheader) + text_start - N_TXTADDR (outheader);

I don't really understand ld too well, so this may not be a
good fix, but it seems to work for me.
