           Summary: Linking with -flto fails
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P3
         Component: lto
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: petr.malik@hotmail.com


Hello.

I've been using CCfits library to write data into FITS files.
The code compiles until I turn LTO on, then it fails with:

lto1: internal compiler error: in lto_wpa_write_files, at lto/lto.c:1518
lto-wrapper: g++ returned 1 exit status
/usr/bin/ld: lto-wrapper failed
collect2: ld returned 1 exit status

The problem seems to appear only after invoking writeArrays() on
CCfits::Column.

OS: Ubuntu 11.04 x64 (2.6.38-8-virtual)
GCC: 4.6.0 (also present in 'gcc-4.6-20110506')
GCC compiled with: --with-arch=native --with-tune=native --enable-threads=posix
--with-fpmath=sse --enable-checking --enable-cloog-backend=isl
IDE: Eclipse CDT 7.0.2

If you do not add --enable-checking the error will vanish.  The check is for
optimality of partitioning and asserts that no partition is empty.

I removed the '--enable-checking' switch and reconfigured GCC 4.6.0, then
compiled my app with this 'new' version, but with the same success as before...

Works for me as stated.
