[Bug binutils/3609] New: `objcopy --only-keep-debug` segfaults in current cvs

[vapier at gentoo dot org]

noticed after upgrading to 2.17.50.0.7 (the 2.17.50.0.6 and older work fine):

$ mkdir build
$ cd build
$ CFLAGS='-pipe -O0 -g' ../configure
$ make all-binutils

$ ./binutils/objcopy --only-keep-debug ./binutils/objcopy ./binutils/objcopy.out
Segmentation fault

$ gdb --args ./binutils/objcopy --only-keep-debug ./binutils/objcopy
./binutils/objcopy.out
Using host libthread_db library "/lib/libthread_db.so.1".
(gdb) r
Starting program: /usr/local/src/gnu/sourceware/build/binutils/objcopy
