           Summary: internal compiler error: in vinsn_detach, at
                    sel-sched-ir.c:1268 on IA-64
           Product: gcc
           Version: 4.5.2
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: sebastian.hegler@tu-dresden.de


Created attachment 23734
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=23734
The preprocessed file (*.i*) that triggers the bug, generated by adding
-save-temps to the complete compilation command, compressed with gzip.

I am trying to compile boost v1.44.0 ("www.boost.org") library on IA-64, which
fails with: 

/home/h0/radar-08/modules-ia64/gcc/4.5.2/bin/../lib/gcc/ia64-unknown-linux-gnu/4.5.2/../../../../include/c++/4.5.2/bits/stl_algobase.h:553:2:
internal compiler error: in vinsn_detach, at sel-sched-ir.c:1268


Important here seems to be the fact that I built GCC with
"--enable-build-with-cxx". Without that option, building my stuff fails
somewhat later on, see bug #48191.



Continuing as per "http://gcc.gnu.org/bugs/#report". Full Terminal output
follows here, the output from "-save-temps" comes as an attachment.

There's actually a plethora of ICEs popping up when using a gcc compiled with
"--enable-build-with-cxx".

I'll file separate reports on those, and mention them here when I'm done.

I have now submitted PR 48218 and PR 48219, which may or may not be related to
this issue. 

What these three have in common is that they only appear when gcc is built with
"--enable-build-with-cxx".

Looks like PR 46518 (the fix was not propagated from trunk to 4.5-branch).  Can
you please check whether below patch fixes these problems?

Yes, this fixes this one, and also the other two (PR 48218 and PR 48219).

I have backported the patch for PR 46518 to 4.5, so fixed.
