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':
../links-current/html_tbl.c:1304:1: internal compiler error: in hoist_code, at
gcse.c:3119
Please submit a full bug report,

lto-wrapper: gcc returned 1 exit status
collect2: error: lto-wrapper returned 1 exit status
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.
