Da seit Wochen IPS ohne Probleme stabil (unter gdb) lief, habe ich mal eben ein Update gemacht 
Anschließend die PHP-Module updaten und sofort eine SIGSEGV erhalten.
Das war ‚früher‘ aber nicht.
Ein continue hilft leider auch nicht wirklich… es folgt eine malloc und IPS ist ‚tot‘.
Und natürlich hat er das Modul nicht geclont, somit ein ‚Teufelskreis‘
Program received signal SIGSEGV, Segmentation fault.
