[Bug binutils/11430] New: nm crashes when handling some lib file.

[hzgmaxwell at sohu dot com]

When listing symbols in a lib file, it crashed here.

#0  coff_slurp_symbol_table (abfd=0x16e3888) at coffcode.h:4519
#1  0x0040f9fc in coff_get_symtab_upper_bound (abfd=0x16e3888) at coffgen.c:338
#2  0x004057ac in _bfd_generic_read_minisymbols (abfd=0x16e3888, dynamic=0,
minisymsp=0xe2cc60, sizep=0xe2cc5c) at syms.c:808
#3  0x0040268e in display_rel_file (abfd=0x16e3888, archive_bfd=0x166b0e0) at
nm.c:1006
#4  0x00402b15 in display_archive (file=0x166b0e0) at nm.c:1147
#5  0x00402c2e in display_file (filename=0xe2cd6d "/d/WebCoreediting.lib") at
nm.c:1195
#6  0x004037d0 in main (argc=2, argv=0x166ae40) at nm.c:1661

Here is the code, the sym variable got a value as 1,
  /* FIXME: We should not be casting between ints and
 pointers like this.  */
  sym = ((coff_symbol_type *)
 ((symndx + obj_raw_syments (abfd))
  ->u.syment._n._n_n._n_zeroes));


then it crashed at
if (sym->lineno != NULL && ! warned)


I'm proposing a solution as below, to check the sym after setting its value.

  //brook
  if(sym < obj_symbols (abfd) ) {
  _bfd_error_handler (_("%B: warning: illegal symbol address %x,
which should be greater than %x"),
  abfd, sym, obj_symbols (abfd));
  continue;
  }

[Bug binutils/11337] windres compiles menus and dialogs to UNICODE not ANSI

I have indeed tried that, to no avail.  What did work was reverting to windres
2.18.  So something between .18 and .20 messed this up.

I've resent the zip including the resource.h now.

Best regards,
Ron

Trying to get backslashes through echo is bound to fail.

:
"If any of the operands contain a  character, the results are
implementation-defined."

Patch

I think a more reliable patch would be something like this, which changes \1 to
\\1.

[Bug ld/11426] New: ld/configure.host does not behave as expected if /bin/sh is dash and not bash

[mgretton at sourceware dot org]

For arm-none-linux-gnueabi ld/configure.host (from CVS HEAD as of 23 March 2010)
executes the following sequence of commands to set HOSTING_CRT0 to the correct
value:

HOSTING_CRT0='-p -dynamic-linker `${CC} --help --verbose 2>&1 | egrep "ld[^
]*\.so" | sed -e "s,.*-dynamic-linker[  ][  ]*\(.*/ld[^ ]*\.so..\).*,\1,"`
`${CC} --print-file-name=crt1.o` `${CC} --print-file-name=crti.o` `if [ -f
../gcc/crtbegin.o ]; then echo ../gcc/crtbegin.o; else ${CC}
--print-file-name=crtbegin.o; fi`'
HOSTING_CRT0=`echo "$HOSTING_CRT0" | sed -e "s,ld\[^ \]\*,ld-linux,g"`

When executed in bash HOSTING_CRT0 is now equal to:
-p -dynamic-linker `${CC} --help --verbose 2>&1 | egrep "ld-linux\.so" | sed -e
"s,.*-dynamic-linker[   ][  ]*\(.*/ld-linux\.so..\).*,\1,"` `${CC}
--print-file-name=crt1.o` `${CC} --print-file-name=crti.o` `if [ -f
../gcc/crtbegin.o ]; then echo ../gcc/crtbegin.o; else ${CC}
--print-file-name=crtbegin.o; fi`

But with dash it is equal to:
-p -dynamic-linker `${CC} --help --verbose 2>&1 | egrep "ld-linux\.so" | sed -e
"s,.*-dynamic-linker[   ][  ]*\(.*/ld-linux\.so..\).*,^A,"` `${CC}
--print-file-name=crt1.o` `${CC} --print-file-name=crti.o` `if [ -f
../gcc/crtbegin.o ]; then echo ../gcc/crtbegin.o; else ${CC}
--print-file-name=crtbegin.o; fi`

(Where ^A is the character with value 1).

This then causes many ld tests to fail if /bin/sh is linked to dash instead of
bash (as is the case for Ubuntu).

My reading of POSIX says that the output of:
echo "\1" 
is implementation defined and so dash's behaviour is acceptable, (as is in this
case bash's).

I believe this issue also affects other targets including x86_64 and mips.

A workaround for these issues is to make the first "exec sh ..." in
get_link_files in ld/testsuite/config/default.exp be "exec bash ..." instead.

ld tests that fail if sh is dash instead of bash are:
