Addix Internet Services GmbH commented on ASTERISK-23717:
---------------------------------------------------------

The patch libxml-z_stream-misuse.diff ist not working with 2.7.6:

libtool: compile:  gcc -DHAVE_CONFIG_H -I. -I. -I. -I./include -I./include -D_REENTRANT -g -O0 -g -O0 -pedantic -W -Wformat -Wunused -Wimplicit -Wreturn-type -Wswitch -Wcomment -Wtrigraphs -Wformat -Wchar-subscripts -Wuninitialized -Wparentheses -Wshadow -Wpointer-arith -Wcast-align -Wwrite-strings -Waggregate-return -Wstrict-prototypes -Wmissing-prototypes -Wnested-externs -Winline -Wredundant-decls -Wp,-MD,.deps/xmlIO.pp -c xmlIO.c  -fPIC -DPIC -o .libs/xmlIO.o

At the moment i cannot test 2.7.7 because of autoconf dependency....

> When loading the xml documentation the asterisk always dies with an segmentation fault. Although this should not influence each other, this only happens when the /etc/asterisk/asterisk.conf has an include to an another file. 
> - When the include in the asterisk.conf is removed the xml documentation is loaded perfectly fine. No segfault.
> - When the xml documentation is remove the include in the asterisk.conf works perfectly fine. No segfault.
> - The segfault always appears (100% reproducible.) when both is used.
