   In "GNU C++ version 1.34.1 (68k, MIT Syntax) 
   compiled by GNU C version 1.34" on a SUN 3, ...

   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);

   if a_data is too big (e.g. 950k) to fit on the call stack, then alloca
   returns garbage, apparently.  Allocating using malloc() (with a
   corresponding 'free(bytes)') fixes the problem, but alloca is used in
   similarly dangerous contexts elsewhere.

   Please don't ask how ugly my program must be 
   to have a data segment of 950k :-)

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
