    There is a bug in gcc 2.7.1, found during compilation of gcc
  building on the alpha, hosted on the alpha, targetted at the i386
  (but this may not reproduce the bug; see my analysis below).  It
  occurs during the compilation of libgcc2.a and produces the
  following output:

..  
  ./xgcc -B./ -O2 -I../../dir-include/include -DCROSS_COMPILE -DIN_GCC   -g -I./include -pic-none  -g1 -D__GCC_FLOAT_NOT_NEEDED -I. -I../../../src/gcc_2_7_1 -I../../../src/gcc_2_7_1/config -c -DL${name} \
      ../../../src/gcc_2_7_1/libgcc2.c -o ${name}.o; \
  if [ $? -eq 0 ] ; then true; else exit 1; fi; \
  /afs/ri/project/fsf/install/alpha-i386/elf/i386-osfrose/bin/ar rc tmplibgcc2.a ${name}.o; \
  rm -f ${name}.o; \

xgcc: Internal compiler error: program cc1 got fatal signal 11
make: *** [libgcc2.a] Error 1

    The following call to cc1 fails (I'll include the .i file at the
  end of this message, though as I say, it may not reproduce the bug):

 ./cc1 /tmp/ccaamBaa.i -melf -mno-underscores -mmcount-ptr -quiet -dumpbase libgcc2.c -g -g1 -O2 -version -o /tmp/ccaamBaa.s
GNU C version 2.7.1 80386, ELF objects compiled by GNU C version 2.7.1.
xgcc: Internal compiler error: program cc1 got fatal signal 11
make: *** [libgcc2.a] Error 1

  Tracking the problem through cc1, I found that it occured upon the
  return from output_constant_pool; the jumping to the return address
  resulted in a jump to never-never land, and a segmentation fault.
  That was because the return address had been overwritten on the
  stack, which occurred on line 494 of real.c in function "endian"
  with the following backtrace:

#0  endian () at ../../../src/gcc_2_7_1/real.c:493
#1  0x12010ff28 in etartdouble () at ../../../src/gcc_2_7_1/real.c:1019
#2  0x1200f5ae4 in assemble_real () at ../../../src/gcc_2_7_1/varasm.c:1826
#3  0x1200fab2c in output_constant_pool ()
    at ../../../src/gcc_2_7_1/varasm.c:3392
#4  0x1200f20d8 in assemble_start_function ()
    at ../../../src/gcc_2_7_1/varasm.c:770
#5  0x1200675b8 in rest_of_compilation ()
    at ../../../src/gcc_2_7_1/toplev.c:3223
#6  0x120043eb0 in finish_function () at ../../../src/gcc_2_7_1/c-decl.c:6791
#7  0x120026938 in yyparse () at /usr/local/gnu/share/bison.simple:311
#8  0x120063dec in compile_file () at ../../../src/gcc_2_7_1/toplev.c:2227
#9  0x120069524 in main () at ../../../src/gcc_2_7_1/toplev.c:3913

  That line is:

	  x[3] = (long) t;

  "x" is a variable sized long array passed into endian from
  etartdouble, which is called from assemble_real through the
  following set of macros:

ASM_OUTPUT_LONG_DOUBLE			(defined in i386.h:1632)
 REAL_VALUE_TO_TARGET_LONG_DOUBLE	(defined in real.h:193) 

  It is defined in ASM_OUTPUT_LONG_DOUBLE:

#define ASM_OUTPUT_LONG_DOUBLE(FILE,VALUE)  		\
do { long l[3];						\
     REAL_VALUE_TO_TARGET_LONG_DOUBLE (VALUE, l);	\
     if (sizeof (int) == sizeof (long))			\
       fprintf (FILE, "%s 0x%x,0x%x,0x%x\n", ASM_LONG, l[0], l[1], l[2]); \
     else						\
       fprintf (FILE, "%s 0x%lx,0x%lx,0x%lx\n", ASM_LONG, l[0], l[1], l[2]); \
   } while (0)

  Note that the array is only of size 3, so assigning into it at index
  3 is an error.  The definition of REAL_VALUE_TO_TARGET_LONG_DOUBLE
  is:

#if LONG_DOUBLE_TYPE_SIZE == 96
#define REAL_VALUE_TO_TARGET_LONG_DOUBLE(IN, OUT) (etarldouble ((IN), (OUT)))
#else
#define REAL_VALUE_TO_TARGET_LONG_DOUBLE(IN, OUT) (etartdouble ((IN), (OUT)))
#endif

  The definition of LONG_DOUBLE_TYPE_SIZE is 64 (in osfrose.h).  This
  overrides the original definition of 96, in i386.h.  So I conjecture
  that this value was overridden in osfrose.h without awareness that
  that required a modification to the array size in the
  ASM_OUTPUT_LONG_DOUBLE definition in i386.h

    What kind of error this memory overwrite causes is obviously very
  dependent on data layout on the stack, which is very dependent on
  what compiler you use to compile gcc with, the phase of the moon,
  etc.  Hence I do not know if the segmentation fault is
  reproducible.  Nonetheless, the above strikes me as a bug by
  inspection; I suggest (but am not sure, since I don't really
  understand the intricacies of the i386 config) that the solution is
  increasing the size of the array defined in ASM_OUTPUT_LONG_DOUBLE
  to 4.
