one.o.000i.cgraph: -fdump-ipa-cgraph for the LTO step for the unpatched GCC
(r221482)

(In reply to Jan Hubicka from comment #8, #9 and #10)

First, I can still reproduce the issue with the unpatched GCC. In addition, the
big program also compiles successfully with -fno-ipa-icf.

Regarding "ld": As /usr/bin/ld is very old, that's with the current "ld" from
the binutils-gdb GIT (via GCC's --with-plugin-ld=) - it fails identical when I
replace the ld.bfd by ld.gold.

Regarding -fdump-ipa-cgraph: If you prefer the dump of a patched version,
please tell me.

Regarding the patch in comment 8 (with "ExTERNAL" typo fixed): Unfortunately,
it doesn't solve the problem - I still get the same ICE.


Regarding the patch in comment 9: I had to change "alias" to "alias_item" due
to

../../gcc/ipa-icf.c:1779:22: error: âaliasâ was not declared in this scope
   if (DECL_EXTERNAL (alias->decl))

but afterwards: It no longer has an ICE!
