           Product: gcc
           Version: 4.6.0

When using the --enable-build-with-cxx bootstrap on x86_64-apple-darwin10 with

http://gcc.gnu.org/ml/gcc-patches/2010-11/msg01803.html

a new ICE appears at -m32 for the gfortran.dg/pr42294.f  -O testcase. This
failure doesn't occur with a normal bootstrap and with the
--enable-build-with-cxx bootstrap is of the form...

Do you know whether this is present on x86_64-linux?

Only occurs for -fPIC on x86_64-apple-darwin10. Adding -fno-PIC on darwin
suppresses the ICE.

I am unable to do a --enable-build-with-cxx bootstrap using...

Is that in relation to bootstrap flags?  There's no PIC flags in the original
report.

The breakage is rather curious.  Build-with-CXX should not cause code
generation differences.  Can you please build normally-bootstrapped compiler
from the same source, build the testcase with the two compilers appending
-fdump-tree-all -fdump-rtl-all and attach the two series of dumps?

Darwin defaults to -fPIC unlike other targets.

Under x86_64 Fedora 10 using...

../gcc/configure --with-gmp=/usr --with-mpfr=/usr --with-mpc=/usr
--prefix=/home/howarth/dist --enable-languages=c,c++,fortran
--enable-build-with-cxx --disable-lto --disable-bootstrap

I get a slightly different crash (which might not be surprising since the
compiler isn't built entirely with -fPIC like on darwin).

I can confirm that this eliminates the ICE (segfault) during the compilation of
gfortran.dg/pr42294.f on x86_64 Fedora10. Will test x86_64-apple-darwin10 next.

I can also confirm that the patch in Comment 10 eliminates the ICE in compiling
gfortran.dg/pr42294.f  -O on x86_64-apple-darwin10 (bootstrapped with
--enable-build-with-cxx) as well. Thanks.
