Hi,

A years ago there was a discussion
(https://gcc.gnu.org/ml/gcc-patches/2004-01/msg02437.html) about
debugging compiler ICEs that resulted in a patch from Jakub, which dumps
useful information into temporary file, but for some reasons this patch
wasn't applied to trunk.

This is the resurrected patch with added GCC version information into
generated repro file.

I've updated the patch that I've posted earlier
(https://gcc.gnu.org/ml/gcc-patches/2014-07/msg01649.html ) according to
recent upstream discussion
(https://gcc.gnu.org/ml/gcc-patches/2014-08/msg00020.html).

The debugging functionality is disabled by default and can be enabled
with adding -freport-bug into compile options. It can be also enabled by
default with
--with-spec during GCC build.

There are several directions in which this can be improved e.g:

1) more user-friendly ways to report bugs (autosubmitting to Bugzilla, etc.)

2) generate repro in case of segfault.

but having basic functionality (autogenerating reprocase in temprorary
file) already seems quite useful.
