[Bug c++/42450] New: another GCC 4.5 ICE on C++ templated code

[Bug c++/42450] New: another GCC 4.5 ICE on C++ templated code

[jacob dot benoit dot 1 at gmail dot com]

Hi,

Thanks to bug #42225 being now fixed, I was able to continue the build of
Eigen's unit tests, and I hit another ICE. It's probably the last one though,
as it occurred at 97% into the build process.

Attached file autodiff.ii.bz2 allows to reproduce it. To reproduce it:

    bunzip2 autodiff.ii.bz2
    g++-svn autodiff.ii

Here the errors happens with GCC SVN from today, December 21.

The same .ii file compiles nicely with GCC 4.4.

My platform is Linux x86-64.

Below is the compiler output when I generated the .ii file:

Confirmed on 4.5. The ICE happens only with -O2, with checking enabled.
I think this should be flagged as P1.

Sorry for the probably uninformed question, but this bug was just tagged
"enhancement", and I thought that "enhancement" meant "not really a bug but
rather a feature request". I would like to understand?

I think it was an accident as this is a P1 bug anyways.

I have a testcase of only 8K but delta is still running. I think I should be
able to reduce it to less than 228 lines.

Testcases from comment #0 and comment #10 don't fail for me (x86_64, r157161).

However, attached testcase does (further reduced from comment #8). Compiler

-O3 ; -O2 ; -O1 -fipa-cp -fipa-sra

Unfortunately, I am not sure that my patch really fixes the issue
rather than hides it.  I'd like to discuss it with Honza first.
Nevertheless, I'll keep working on this.
