Re: FAIL Env-C-0.07 x86_64-linux-thread-multi-ld 2.6.22.10

Ok, so 0.06 had the same problem. That's what I needed to check.

Now, I can't reproduce the problem. So if someone else who can reproduce
it could look at the issue, that would be great. I think the difference
is x64, but it could be something else.

Dear Stas Bekman,

Hi. This is imacat from Taiwan.

I have digged into your code for that "panic: free from wrong pool
during global destruction". It seems to be caused by calling setenv()
at line 75 in your C.xs, which threw out an error in libperl.so in Perl
5.10. Further investigation turns out that, according to:

http://search.cpan.org/dist/perl/INSTALL#Environment_access

Perl write to the memory directly when implementing putenv(), which
might cause problem. To avoid that and use the safe (but potentially
leaky) system putenv() you may set PL_use_safe_putenv = 1.

The above does work for my Perl 5.8.8 and 5.10.0 on x86_64. I do
not know if there will be any side effect on other platforms. I made a
simple patch below, in the hope that it helps. Please tell me if you
need any more information, or if I could be of any help. Thank you.

Thank you for the patch imacat from Taiwan - would please be so kind to
try the attached version?

It works. The terminal log is attached below. Please tell me if
you need any more information, or if I could be of any help.
