Symbol "Perl_hv_undef_flags" problem using rlm_perl

30 Aug 2011

      Greetings,

I have installed a Debian 6 stable on a 64b machine.

Using the factory freeradius-2.1.10 and perl-5.10.1 I got a symbol lookup 
problem, which sounded weird enough... So I downloaded both last stable 
versions (Freeradius-2.1.11 and Perl 5.14.1) and compiled them myself, 
making sure that all Perl symbols were available (I compiled everything 
with -g and -fPIC where it made sense). Using perlbrew I made sure that 
Freeradius was indeed finding the right Perl version and everything 
compiled and installed perfectly.

However, when making some testing on localhost with radtest the problem 
reappeared (with exactly the same error as the debian packaged versions). 
I am not sure why this is failing, as the symbols are, indeel, available 
in libperl.a. I include the complete output of radiusd -X below with both 
the correct localuser test and the failed one.

Thanks in advance for any hints.
