Bug #101196 for Term-ReadLine-Gnu: New segfaults with Term::ReadLine::Gnu 1.25

Hello, We're getting segfaults with perl 5.18.2 + readline 5.1 + Term::ReadLine::Gnu 1.25, on Centos 5. The readline comes from from Centos's readline-5.1-3.el5 RPM. I'm using Terminal.app locally and ssh+screen to reach the host where Term::ReadLine is installed. The rest of this setup works fine with Term::ReadLine::Gnu 1.24. ------------------------------------------------------------------------ % perl -V Summary of my perl5 (revision 5 version 18 subversion 2) configuration: Platform: osname=linux, osvers=2.6.18-371.11.1.el5, archname=x86_64-linux-thread- multi uname='linux 2.6.18-371.11.1.el5 #1 smp wed jul 23 15:12:55 edt 2014 x86_64 x86_64 x86_64 gnulinux ' config_args='-Dprefix=/home/grazzini/.plenv-centos5/versions/5.18.2 -de -Dusedevel -Dusethreads -A'eval:scriptdir=/home/grazzini/.plenv-centos5/ versions/5.18.2/bin'' hint=recommended, useposix=true, d_sigaction=define useithreads=define, usemultiplicity=define useperlio=define, d_sfio=undef, uselargefiles=define, usesocks=undef use64bitint=define, use64bitall=define, uselongdouble=undef usemymalloc=n, bincompat5005=undef Compiler: cc='cc', ccflags ='-D_REENTRANT -D_GNU_SOURCE -fno-strict-aliasing -pipe -fstack-protector -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64', optimize='-O2', cppflags='-D_REENTRANT -D_GNU_SOURCE -fno-strict-aliasing -pipe -fstack-protector -I/usr/local/include' ccversion='', gccversion='4.1.2 20080704 (Red Hat 4.1.2-54)', gccosandvers='' intsize=4, longsize=8, ptrsize=8, doublesize=8, byteorder=12345678 d_longlong=define, longlongsize=8, d_longdbl=define, longdblsize=16 ivtype='long', ivsize=8, nvtype='double', nvsize=8, Off_t='off_t', lseeksize=8 alignbytes=8, prototype=define Linker and Libraries: ld='cc', ldflags =' -fstack-protector -L/usr/local/lib' libpth=/usr/local/lib /lib /usr/lib /lib64 /usr/lib64 /usr/local/lib64 libs=-lnsl -ldb -ldl -lm -lcrypt -lutil -lpthread -lc perllibs=-lnsl -ldl -lm -lcrypt -lutil -lpthread -lc libc=libc-2.5.so, so=so, useshrplib=false, libperl=libperl.a gnulibc_version='2.5' Dynamic Linking: dlsrc=dl_dlopen.xs, dlext=so, d_dlsymun=undef, ccdlflags='-Wl,-E' cccdlflags='-fPIC', lddlflags='-shared -O2 -L/usr/local/lib -fstack-protector' Characteristics of this binary (from libperl): Compile-time options: HAS_TIMES MULTIPLICITY PERLIO_LAYERS PERL_DONT_CREATE_GVSV PERL_HASH_FUNC_ONE_AT_A_TIME_HARD PERL_IMPLICIT_CONTEXT PERL_MALLOC_WRAP PERL_PRESERVE_IVUV PERL_SAWAMPERSAND PERL_USE_DEVEL USE_64_BIT_ALL USE_64_BIT_INT USE_ITHREADS USE_LARGE_FILES USE_LOCALE USE_LOCALE_COLLATE USE_LOCALE_CTYPE USE_LOCALE_NUMERIC USE_PERLIO USE_PERL_ATOF USE_REENTRANT_API Built under linux Compiled at Oct 29 2014 10:56:34 %ENV: PERL5LIB="/home/grazzini/git/dev/local/centos5/v5.18.2/lib/perl5" @INC: /home/grazzini/git/dev/local/centos5/v5.18.2/lib/perl5/x86_ 64-linux-thread-multi /home/grazzini/git/dev/local/centos5/v5.18.2/lib/perl5 /home/grazzini/.plenv-centos5/versions/5.18.2/lib/perl5/ site_perl/5.18.2/x86_64-linux-thread-multi /home/grazzini/.plenv-centos5/versions/5.18.2/lib/perl5/site_perl/5.18.2 /home/grazzini/.plenv-centos5/versions/5.18.2/lib/perl5/5. 18.2/x86_64-linux-thread-multi /home/grazzini/.plenv-centos5/versions/5.18.2/lib/perl5/5.18.2 . ------------------------------------------------------------------------ % perl Makefile.PL verbose Found `/usr/lib64/libtermcap.a'. cc -D_REENTRANT -D_GNU_SOURCE -fno-strict-aliasing -pipe -fstack-protector -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -DHAVE_STRING_H rlver.c -o rlver -fstack-protector -L/usr/local/lib -lreadline -ltermcap It seems that you have the GNU Readline Library version 5.1. cc -D_REENTRANT -D_GNU_SOURCE -fno-strict-aliasing -pipe -fstack-protector -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -DHAVE_STRING_H -DTRG_READLINE_VERSION=0x0501 rlmalloc.c -o rlmalloc -fstack-protector -L/usr/local/lib -lreadline -ltermcap Checking if your kit is complete...
