Hi monks,
i am getting an error message like this
free(): invalid pointer 0x804c690!when i execute a C file which calls a perl program which has "USE DBI" inside it.The C code is given below
#include<stdio.h>
#include <EXTERN.h>
#include <perl.h>
static PerlInterpreter *my_perl;
/*-----------------------------------------------------------
for dynamic loading of perlmodules which inturn uses C libraries
-----------------------------------------------------------*/
static void xs_init (pTHX);
EXTERN_C void boot_DynaLoader (pTHX_ CV* cv);
EXTERN_C void xs_init(pTHX)
{
char *file = __FILE__;
newXS("DynaLoader::boot_DynaLoader", boot_DynaLoader, file);
}
/*-------------------------------------------------------------*/
void CheckBrowserCompat(char *fileName)
{
int count;
dSP;
ENTER;
SAVETMPS;
PUSHMARK(SP);
XPUSHs(sv_2mortal(newSVpv(fileName,0)));
PUTBACK;
count = call_pv("MAIN", G_ARRAY);
SPAGAIN;
printf("COUNT : %d\n",count);
while(count--!=0)
printf("%s",POPp);
PUTBACK;
FREETMPS;
LEAVE;
}
int main (int argc, char **argv, char **env)
{
char *my_argv[] = { "", "browserCompat.pl" };
char fileName[]= "toolbox.html";
my_perl = perl_alloc();
perl_construct( my_perl );
perl_parse(my_perl, xs_init, 2, my_argv, NULL);
//perl_run(my_perl);
CheckBrowserCompat(fileName);
perl_destruct(my_perl);
perl_free(my_perl);
}
Could any one help me.But the program is working correctly and produces the correct output. But along with output it produces the error message.I need some method to avoid this error. Also i please tell me why "perl_run" is used.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>

-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
