I use shm_(put|get)_var() which serialize the stuff when puting and unserialize it when getting. Now I have a fuzzy idea about it: I have an array $users_array which is stored in shm. But when I first call shm_attach (so when it does the proper allocation of segment) there is no $users_array there, so shm_get_var() must fail on getting $users_array. With php3.0.12 I test that with is_array($users_array), and if it's not I know it must be the first call so I have to do the init() stuff. Now, I think it fails because there's no $users_array in shm at the moment I call shm_get_var() which tries to unserialize an unexisting variable. > > On Mon, 9 Aug 1999, Teodor Cimpoesu wrote: > > > (gdb) run -X > > Starting program: /opt/apache2/bin/./httpd -X > > > > Program received signal SIGSEGV, Segmentation fault. > > 0x8095191 in php3api_var_unserialize (rval=0xbfffe43c, p=0xbfffda4c, > > max=0x4019f03c "") at var.c:314 > > 314 (*rval)->type = IS_LONG; > > (gdb) list > > 309 } > > 310 (*p)++; > > 311 if (cur == 'b') { > > 312 (*rval)->type = IS_BOOL; > > 313 } else { > > 314 (*rval)->type = IS_LONG; > > 315 } > > 316 INIT_PZVAL(*rval); > > 317 (*rval)->value.lval = atol(q + 2); > > 318 return 1; > > > > is there any (related) bug to this? > > I searched the bugs.php.net but didn't find, so I submited a new one > > (#2003) > > config: RH6, PHP4 latest CVS (9-Aug-99), Apache-1.3.8-dev. > > > > -- > > CIMPOESU Teodor, Web Programmer > > > > @ DIGICOM S.A.
