      ld++ exits with a segmentation fault when fed source files with large
      data segments.  The fault is caused by an attempt to 'alloca' a large
      chunk of memory in 'copy_data()' in ld.c

	      bytes = (char *) alloca (entry->header.a_data);

   This problem may be fixable by doing this:

	   unlimit stacksize

   Or, do this:

	   limit

   see what the limit of stacksize is (say 2048K), multiply it by 4, and
   set a new limit:

	   limit stacksize 8192



That did the trick -- "ulimit -s 8192" in ksh.

Thanks,
 Othar
