Follow-up Comment #15, bug #50398 (project octave):

I have this problem when compiling Octave 4.2.1 from source on CentOS 7.4. I
use the following configure options:

./configure LLVM_CONFIG=/usr/bin/llvm-config --prefix=/usr/local/octave
--enable-threads=posix --enable-jit --enable-address-sanitizer-flags
--disable-java --with-openssl --disable-float-truncate --enable-bounds-check

My LLVM version is 3.4.2, so according to the previous comment it should build
without an error, but it doesn't.

I have the following error:

../libinterp/corefcn/jit-typeinfo.cc:216:1: error: ‘octave_jit_octave’ has
not been declared
 octave_jit_octave::err_nan_to_logical_conversion (void)
../libinterp/corefcn/jit-typeinfo.cc: In function ‘void
../libinterp/corefcn/jit-typeinfo.cc:216:1: error: redefinition of ‘void

It would be good to have this bug re-opened or at list get a link where it is
explained how to workaround this issue. Thank you!
