I'm sorry. only failed on mingw32. arm-none-eabi- is OK

I will rebuild a clean version to verify this these days.

If I added the '-fno-exceptions' flag, the ICE disappearsed. My g++ is built
with SJLJ exception support. I think both Linux/x86 and arm-none-eabi are using
DW exception.

I rebuilt a version with '--disable-sjlj-exceptions --with-dwarf2', but the ICE
still exists. Maybe it's mingw32 only?

Still fails with r169851. 
Both Linux/x86 and arm-none-eabi versions are OK. Seem it is mingw32 (maybe
also cygwin ?) only.

mingw32-gcc -c -O2 test.cpp                          --  ICE
mingw32-gcc -c -O2 -fno-exceptions test.cpp          --  OK
mingw32-gcc -c -O2 -fno-partial-inlining test.cpp    --  OK

I used git-bisect and found it is caused by r166555.

Created attachment 23292
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=23292
dump files

Well, it not caused by r166555, just exposed by r166555. 
The first difference in the dump files between r166555 and the prev-versions is
that r166555 make sfTextCtrlBase::~sfTextCtrlBase() inline into
sfTextCtrl::sfTextCtrl(void*).  

This attachment is the dump files against trunk.  Hope it be useful.
