It looks as if my reduction was invalid. My cvise script was
as follows:
/usr/bin/gcc -w bug1071.c && (ulimit -t 10 ; ./a.out 1 | grep "g_90 :
F239C101") \
&& /home/dcb40b/gcc/results/bin/gcc -w -O2 -Werror=uninitialized \
-Werror=aggressive-loop-optimizations -Werror=sequence-point bug1071.c \
&& (ulimit -t 10; ./a.out 1 | grep "g_90 : B01CC67C")
I am a little bit surprised the Werror-uninitialized didn't catch
the local variable read of __trans_tmp_5.
