------- Comment #10 from hvreddy1110 at gmail dot com  2006-08-22 14:28 -------

Hi,
I used and Xfree86-4.4 and 4.5 with gcc-3.4.3
But both the time it is giving same problem as

slicer.cc: In function `void triangulateRect(Arc*, Backend&, int, int, int)':
slicer.cc:382: internal compiler error: in verify_local_live_at_start, at
flow.c:546
What could be the problem.

Thanks

Regards,
Harsha

http://sources.redhat.com/ml/crossgcc/2005-05/msg00154.html
is a report of a similar problem with
gcc-3.4.3.  xfree86-4.5.0's fontutils.c causes an ICE when 
compiled with -O3 -fno-strict-aliasing.  Backing down to xfree86-4.4.0,
or using -O2, or not using -no-strict-aliasing, or using gcc-4.0.0,
makes the problem go away.  I'll attach a reduced testcase.
To reproduce, do
$ arm-unknown-linux-gnu-gcc -O3 -fno-strict-aliasing   -c fontutils.i
Error is
fontutils.i:44: internal compiler error: in verify_local_live_at_start, at
flow.c:546

Is this the same problem, or should I file a new report?

Seeing the same bug with gcc 3.4.2 on armv4b when compiling x.org 6.8.1.
This does not happen with gcc 3.3.4.
