efree() crash when used in a shutdown function

Hi,

From the pecl/printer extension:

static void php_printer_shutdown(zend_printer_globals *printer_globals
TSRMLS_DC) {
if (printer_globals->default_printer) {
efree(printer_globals->default_printer);
}
}

PHP_MINIT_FUNCTION(printer)
{
ZEND_INIT_MODULE_GLOBALS(printer, php_printer_init,
php_printer_shutdown);
..

This code fails when the module is shutting down. The mudule is compiled
against PHP5, and it works fine with PHP4.

If I change efree() to free() (and change the estrdup() to strdup()) the
code works fine. I have checked the string just before calling efree and
it is allocated and has a value.

Is there any problem calling efree() from a shutdown function ?

Hi,

stdlib.h is included in line 106 of bindlib_w32\conf\portability.h.
This
causes the linker to look for __pctype and __mb_cur_max. This is not a
problem for the old style builds but with Wez' new build system it
causes
a linking problem.

Removing line 106 form this file solves the problem and as far as I can
tell it does not cause any other problems.
