glob

[Emanuele Matli]

Hi,

I have a problem using glob on my cgi perl program.
If I try to call glob twice the program crashes giving one of this errors:

*** malloc[2302]: error for object 0xbffffe20: Pointer being reallocated
was not allocated
Out of memory!

*** malloc[2396]: Deallocation of a pointer not malloced: 0x65726c00;
This could be a double free(), or free() called with the middle of an
allocated block; Try setting environment variable MallocHelp to see
tools to help debug
Segmentation fault

I'm using perl, v5.8.1-RC3 on MAC OSX.

Thanks,

E.

Are you sure that these are Perl errors?

I grepped the Perl documentation for 'malloc'
(http://search.cpan.org/grep?release=perl-5.8.6&string=malloc&i=1&n=1)
and couldn't locate any such phrases as "error for object" or
"Deallocation of a pointer".

Could you please present the Perl code which is causing the problems?
We would then have a better chance at diagnosing them. Thanks.

No, they would be perl errors, not Perl errors. That is, errors from
the implementation of perl (which is implemented in the C language, and
thus gives C errors, not Perl errors).

And version information, too.

No, they would be perl errors, not Perl errors. That is, errors from

That was my hunch when I saw the "*** malloc[2396]", but since I don't
know enough C to competently answer questions about it, I spoke cautiously.

In any case, in response to another question by the OP, Sherm Pendley
noted that the OP needs to install X Code. Which makes sense to me,
'cause I know that when I first went to use Perl after I had gotten my
iBook, I was in a panic until I learned (from Randal, dha and others)
about installing those development tools.
