--- Comment #2 from David Binderman <dcb314 at hotmail dot com> ---
I see something similar when attempting a bootstrap with asan & ubsan on
current gcc trunk:
gcc/expmed.cc:3288:26: runtime error: signed integer overflow:
-9223372036854775808 - 1 cannot be represented in type 'long int'
Configure is:
../trunk/configure \
--disable-multilib \
--disable-werror \
--with-build-config=bootstrap-asan \
--with-build-config=bootstrap-ubsan \
--enable-checking=df,extra,fold,rtl,yes \
--enable-languages=c,c++,fortran
And there are extra flags added to the top level Makefile:
sed 's;-O2;-O3 -march=native;' < Makefile > Makefile.tmp
diff Makefile Makefile.tmp
mv Makefile.tmp Makefile
I wonder if this is a regression for gcc-14.
