[Message part 1 (text/plain, inline)]

I've been playing around with compiler options. From my findings, the
-foptimize-sibling-calls flag breaks the build:

./autogen.sh
CFLAGS='-g3 -O1 -gdwarf-2 -foptimize-sibling-calls' \
./configure --with-native-compilation
make

OTOH, using -O1 with every flag listed under -O2 *but*
-foptimize-sibling-calls results in the build succeeding. The following
works as well for me:

./autogen.sh
CFLAGS='-g3 -O2 -gdwarf-2 -fno-optimize-sibling-calls' \
./configure --with-native-compilation
make
