Package: gcc-4.7
Version: 4.7.2-5
Severity: normal
Tags: upstream
Dear Maintainer,
Compiling the attached program with
gcc -std=c99 test.c -o test -Wall -Wextra -O2
results in
test.c: In function ‘pow2_s’:
test.c:3:7: internal compiler error: in build2_stat, at tree.c:3785
but works fine without the -O2 flag.
