------- Comment #6 from ubizjak at gmail dot com  2009-09-18 15:29 -------
This revision also fails to bootstrap on alphaev68-unknown-linux-gnu (revision
151799 is OK). stage2 compiler segfaults trying to build libgcc:

configure:3232: /home/uros/gcc-build/./gcc/xgcc -B/home/uros/gcc-build/./gcc/
-B
/usr/local/alphaev68-unknown-linux-gnu/bin/

/usr/
local/alphaev68-unknown-linux-gnu/sys-include    -c -g -O2 -mieee  conftest.c

conftest.c:1:1: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

In fact, stage2 cc1 segfaults on everything:

As mentioned in comment #1, debug info is missing/meaningless.

gcc was built with default configure flags:

~/gcc-build/gcc/xgcc -v    
Using built-in specs.
Target: alphaev68-unknown-linux-gnu
Configured with: ../gcc-svn/trunk/configure --enable-languages=c,c++,fortran
Thread model: posix
gcc version 4.5.0 20090917 (experimental) [trunk revision 151835] (GCC) 

(don't bother with revision number, it was patch-reversed to 151800).
