I'm not specifying anything strange and even if I use -O0 the result is the same: /localbuild/build/sysnative-prencurses-5.9/narrowc/Ada95/src$ gnatmake -O0 -P/ncplc/src/sysnative-prencurses-5.9/Ada95/src/library.gpr -XBUILD_DIR=`cd ..;pwd` -XSOURCE_DIR=`cd ..;pwd` -XSOURCE_DIR2=`cd /localbuild/src/sysnative-prencurses-5.9/Ada95/src;pwd` -XLIB_NAME=AdaCurses -XSONAME=libAdaCurses.so.1 -XLIB_KIND=static gcc -c -g -O2 -gnatafno -gnatVa -gnatwa -O0 -I- -gnatA /localbuild/src/sysnative-prencurses-5.9/Ada95/src/terminal_interface-curses-menus.adb raised STORAGE_ERROR : stack overflow (or erroneous memory access) GCC 4.4 works fine (I don't have GNAT 4.5 here to test)
