compile mod_php with-mm on RedHat 7 with oonly 34M of shared memory. Also compile apache to use mod_php (enable_module=most) ps_mm_initialize calls mm_create() and passes 0 for pool size. That causes mm_create to try to get hardcoded 67M of shared memory. mm_create fails b'zeachine only has 34M ofshared memory available. As a result, data->mm is NULL and data->hash will also be assigned to NULL returned from mm_caloc, which will later cause a crash in ps_mm_destroy. This means that apache crashes on startI think ps_mm_initialize should check the
return from mm_create and pass something other than 0 to it.
