| Subject: | Segmentation fault in Debian Linux |
Hi,
I had a lot of problems testing/installing the module in Debian in a self-compiled perl.
To make a long story short, here is what I hacked in Tcl.pm to make it work:
$ diff -u . blib/lib/Tcl.pm

}
I really have no clue why the PERL_DL_NONLAZY environment variable has to be set, but I
noticed that the tests were fine and the programs segfaulted so I tried it.
I hope this might help someone in the meanwhile, cheers,
Flavio.
