[Swig-user] corrupt perl strings > 976 bytes on x86_64

[Matt L. <law...@ya...>]

Hey,

I ran into a problem today I hadn't seen before.  I am
wrapping C++ with perl.  In one function where a
string is used as the function return value (by string
I mean const char *) the returned string is partially
garbled when it's returned to perl.  The string is
correct in C++ before passing back.

This is swig 1.3.33.  I also tried 1.3.31 which gave
me a slightly different garbled result.  Interesting
though, in both cases it was garbled after 976 bytes. 
e.g. the first 976 bytes were correct, after that it
was garbled, truncated, and/or the wrong length.  I
have been using swig successfully for quite a while
but I am relatively new to 64-bit Linux, so I think
this is the culprit.

Platform is a vanilla centos5 (x86_64).  The problem
does NOT occur using php5 wrappers, only perl.  The
problem also does not occur with perl in freebsd or
32-bit linux (centos4 I think)

I realize that's not much to go on; I will attempt to
create a test case that can illustrate the problem. 
But I wanted to shout out and see if this sounded
familiar to anyone.  Thanks.
