Introduction:

Perl "appears" horribly broken on gentoo for many things, some of them
probably gcc-3.2 related. I'm working through them and will drop bugs in
as I find issues, unless anyone tells me not to. Useful information for
logging purposes is enclosed.

The Problem:

The attached info relates to the command:

valgrind perl -MTerm::ReadLine -e 'new Term::ReadLine("foo");'

(CPAN.pm segfaults on exit using this ReadLine package, this is the 
simplest test case).

Information:

(perl)
This is perl, v5.8.0 built for i686-linux

config_args='-des -Darchname=i686-linux -Dcccdlflags=-fPIC 
-Dccdlflags=-rdynamic -Dcc=gcc -Dprefix=/usr -Dvendorprefix=/usr 
-Dsiteprefix=/usr -Dlocincpth=  -Doptimize= -g -Duselargefiles -Dd_dosuid 
-Duseshrplib -Dman1ext=1 -Dman3ext=3pm -Dlibperl=libperl.so.1.5.8 
-Dd_dosuid -Dd_semctl_semun -Dcf_by=Shevek -Ud_csh -Di_gdbm -Di_db 
-Di_ndbm'

Then tweaked config.sh to make SIGRTMIN be 32 not -1 before running 
'make'.

Thread model: posix

(system)
CFLAGS for most things were:
	CFLAGS="-mcpu=pentium3 -march=pentium3 -O3 -pipe"
in /etc/make.conf

I will be using more valgrind to see what else I can dig up.

I am the Borg.

sub AUTOLOAD{my$i=$AUTOLOAD;my$x=shift;$i=~s/^.*://;print"$x\n";eval
qq{*$AUTOLOAD=sub{my\$x=shift;return unless \$x%$i;&{$x}(\$x);};};}

foreach my $i (3..65535) { &{'2'}($i); }
