Re: [PHP4BETA] crash in lastest CVS (patch included)

Thanks. That patch is correct. I fixed it in the CVS. Andi At 03:14 PM 8/9/99 +0200, Thies C. Arntzen wrote:

hi, the script that crashes is pretty complicated (zeev knows). the actual script snippet is:

          switch ($mymimetype)
            {
              default:
                $mysize = false;
                $mytag  = false;
                break;
            }

changing this to

        switch ($mymimetype)
            {
              default:
                $mysize = 0;
                $mytag  = 0;
                break;
            }

fixes the crash. also reverting to zend_execute.c to 1.68 fixes the problem! the attached patch is my "best guess" for the problem. gdb says: Program received signal SIGSEGV, Segmentation fault. 0x31e98 in _efree (ptr=0x9af964) at /dot/dc4/zend/cgi-debug/../php4/libzend/zend_alloc.c:180
