[Bug gas/11050] New: Build error in tc-arm.c

[rcc at zubira dot com]

Using the following:

gcc -v
Using built-in specs.
Target: i486-linux-gnu
Configured with: ../src/configure -v --enable-languages=c,c++,fortran,objc,obj-
c++,treelang --prefix=/usr --enable-shared --with-system-zlib --
libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --enable-
nls --with-gxx-include-dir=/usr/include/c++/4.2 --program-suffix=-4.2 --enable-
clocale=gnu --enable-libstdcxx-debug --enable-objc-gc --enable-mpfr --enable-
targets=all --enable-checking=release --build=i486-linux-gnu --host=i486-linux-
gnu --target=i486-linux-gnu
Thread model: posix
gcc version 4.2.4 (Ubuntu 4.2.4-1ubuntu4)

I get the following error whilst building:

binutils-2.20/configure --target=arm-elf --prefix=/home/user/tools/arm-elf

../../binutils-2.20/gas/config/tc-arm.c: In function ‘make_mapping_symbol’:

        frag->tc_frag_data.first_map = symbolP;
      }
    if (frag->tc_frag_data.last_map != NULL)
+     {
        know (S_GET_VALUE (frag->tc_frag_data.last_map) < S_GET_VALUE 
(symbolP));
+     }
    frag->tc_frag_data.last_map = symbolP;
  }

The above seems to fix the build.
