Mark,
i have compiled and installed your posted version of nsperl2 on
Mac OS X 10.5.2 against aolserver 4.5 from head, and it does not crash.
Are you sure, you linked nsperl2 against the same tcl version, with the
same alloc implementation? What other modules are you loading?
The invalid block message shows typically up, when there is a double
free issued.

Slight prototype fix to my .c file, but no change to the issue/

Hi all,
So I'm trying to write a new loadable module. From a combination of
example modules I thought I was set, but I have this frustrating
roadblock I can't figure out.
As soon as I have a Tcl_CreateCommand in my code, the server startup
crashes with alloc: invalid block. I have attached my .c and Makefile
if anyone has time to cast their eye over it? I think I'm missing some
difference with Aolserver 4 since Vlad's nsfortune shows the same
issue and I assume that used to work once! Unless I have a problem
with my aolserver still, but nslog works fine and that obviously does
Tcl_CreateCommand...
Here is my log output:

Abort trap
The before, after shows the Tcl_CreateCommand returns. The stack on
exit looks something like:

Unfortunately as I mentioned in my compile issue email I have not been
able to compile against a debug-symbol Tcl so I can't trace past
Ns_TclDestroyInterp.
Thanks for your time - I'm going nuts here!
Mark.
