For the last few days, since April 8th, I get bootstrap failures on 
mainline like this:

stage1/xgcc -Bstage1/
    -B/ices/bangerth/tmp/build-gcc/gcc-install/i686-pc-linux-gnu/bin/ -c -g
    -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes
    -Wmissing-prototypes -pedantic -Wno-long-long -Wno-variadic-macros
    -Wold-style-definition -Werror -fno-common   -DHAVE_CONFIG_H    -I. -I.
    -I../../gcc/gcc -I../../gcc/gcc/. -I../../gcc/gcc/../include
    -I../../gcc/gcc/../libcpp/include  ../../gcc/gcc/tree-ssa-pre.c -o
    tree-ssa-pre.o
../../gcc/gcc/tree-ssa-pre.c: In function 'execute_pre':
../../gcc/gcc/tree-ssa-pre.c:1812: sorry, unimplemented: inlining failed in call to 'create_value_expr_from': recursive inlining
../../gcc/gcc/tree-ssa-pre.c:1853: sorry, unimplemented: called from here
make[1]: *** [tree-ssa-pre.o] Error 1


The failure happens in a piece of code that was added here:
    http://gcc.gnu.org/ml/gcc-bugs/2005-04/msg00337.html
by Dan Berlin (it introduced the recursive calls), though it certainly 
isn't the cause, just the trigger. It also was added already April 4th.

Since this has been happening for the last 10 days for me, I start to 
believe that I may be the only one seeing this. Anyone any explanations?

Thanks
    Wolfgang

bootstrap compiler is Mandrake's gcc 3.3.2.
