Description

After adding the mod_proxy_core server module I get a bus error when starting lighttpd.

$ gdb sbin/lighttpd

jan, i looked into it a bit. as first patch i added:


Index: src/array.c
===================================================================
--- src/array.c (revision 1820)
+++ src/array.c (working copy)
@@ -85,6 +85,7 @@
    int ndx = -1;
    int i, pos = 0;

+       if (a == NULL) return -1;
    if (key == NULL) return -1;

    /* try to find the string */

the real issue is imho that after


array *status = status_counter_get_array();

the array is null. it seems status_counter_init isnt called. could it be a threading issue?
