Thanks for the bug report, but I can't debug this problem without more verbose test output. Could you rerun the tests in verbose mode? From the distribution directory, please try running the following: perl -Ilib t/01basic.t Thanks, Steffen

Of course. I apologize. Here's what I got: fivesix# perl -Ilib t/01basic.t 1..10 ok 1 - use Math::SymbolicX::Inline; ok 2 - basic example ok 3 - basic example outputs correct results ok 4 - external sub example Segmentation fault (core dumped) I don't have debugging symbols in (that needs to change) but here's what the trace gives me, for what it's worth: fivesix# gdb /usr/local/bin/perl perl.core GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.

Given this module is a pure-Perl module and all of its non-core dependencies are, too, I doubt the problem lies within Math::SymbolicX::Inline. Furthermore, I haven't seen this problem on any perl >= 5.8.0, so I would guess it's a bug in 5.6.x. Could you try running the tests under 5.8 in the same environment? I won't compile a 5.6.2 "just" to track down this issue. It's not that I don't want to, I just can't afford to spend the time. Sorry! Steffen

No problem, Steffen! The choice to support older Perls is always the authors. The only reason I reported it was because v1.00 didn't have the same incompatibility. For now I'll update the FreeBSD port entry to v1.01 and require Perl 5.8+. (My 5.8 tests don't encounter any problems.) I'll do a little diff-ing between v1.00 and 1.01 and see if there's a trivial way to reintroduce backward compatibility. If so, I'll send you a patch. Thanks for your time!

Well, as you no doubt already knew, there were no substantial code changes between 1.00 and 1.01, only test changes, so something odd is happening with that test 5. I'll be taking a closer look in the next little while and will let you know if I find anything.
