Bug #12806: Compiling ruby 2.3.1 on HPUX 11.31 ia64 breaks in segmentation fault

PROBLEM: 

The https://bugs.ruby-lang.org/issues/8793 is still not resolved.

I've tried to compile ruby-2.3.1 on HP-UX B.11.31 ia64.

The compile phase gets to the phase:

echo generating encdb.h
./miniruby -I./lib -I. -I.ext/common  ./tool/generic_erb.rb -c -o encdb.h ./template/encdb.h.tmpl ./enc enc

But then breaks with:

$ gmake       
        CC = cc
        LD = ld
        LDSHARED = ld -b
        CFLAGS =  -g  
        XCFLAGS = -DRUBY_EXPORT
        CPPFLAGS =   -I. -I.ext/include/ia64-hpux11.31 -I./include -I.
        DLDFLAGS = -E -Wl,-E  
        SOLIBS = 
linking miniruby

Any hints on what is causing this?

I've tried compiling both with gcc (4.7.1 and 4.6.3) and HP C/aC++ B3910B A.06.28 (the example above)
