preprocessed files to reproduce the bug

When using flags "-ftrapv -flto -fwhole-program -O2" on PA-RISC, gcc fails
with an internal error:

In file included from ../links-current/url.c:574:0,
                 from ../links-current/url.c:539,
                 from :121:
../links-current/html_tbl.c: In function 'display_table_frames':

make: *** [links] Error 1

I'm attaching preprocessed files to reproduce the bug --- extract the archive
parisc-flto-trapv-crash.tar.xz on Linux PA-RISC and run make to get the crash.

gcc-4.6.3 has this bug too.
