I compile a cross compiler --host=x86_64-redhat-linux-gnu
--target=x86_64-pc-mingw32,
Then use this cross compiler to compile a native binutils and gcc,
Then I run the native x86_64-pc-mingw32-g++.exe which call native
as.exe under winxp x64.
It produce such error :
$ /c/tools/target/bin/x86_64-pc-mingw32-g++.exe -v -Wall hello.cpp
Using built-in specs.

Assertion failure in obj_coff_endef at
../../binutils/gas/config/obj-coff.c line 780.
Please report this bug.

I read the source code binutils/gas/config/obj-coff.c 780 line it is :
778 if (SF_GET_FUNCTION (def_symbol_in_progress))
779 {
780 know (sizeof (def_symbol_in_progress) <= sizeof (long));
781 set_function (def_symbol_in_progress);
782 SF_SET_PROCESS (def_symbol_in_progress);
x86_64-pc-mingw32 has a ABI that pointer is 8 bytes and int / long is 4 bytes,
so maybe sizeof( pointer ) <= sizeof(long) is not true.
I remove this line and compile a new as.exe, then run g++, it print
out this log :
$ /c/tools/target/bin/x86_64-pc-mingw32-g++.exe -v -Wall hello.cpp
