Gentoo don't start liquidsoap

Andrey Podshivalov added a comment - 03/Nov/10 6:42 PM - edited What "bug" is it? segfault? Is gentoo "hardner" a security hardened version? If so, do you have any explanation or link to why clone() is considered unsafe? yes bug is segfault (sorry i'm missing to tell that) I thinks it's clone() because strace en gdb stop juste avec clone() The thread 2 is locked on a select. The segfault is more likely to occur in thread 1, where ocaml-pcre is used. Could you please try to rebuild ocaml-pcre and then liquidsoap? confirm this. i've rebuild my pcre-ocaml(5.15.0) package and liquidsoap and nothing changes. i cant install liquidsoap with "make install", because liqi crashes(i think with pcre too). {{{ $ make install make -C liquidsoap-0.9.0 install make[1]: Entering directory `/home/somebody/Desktop/liquidsoap-full-0.9.0/liquidsoap-0.9.0' make -C doc doc-install make[2]: Entering directory `/home/somebody/Desktop/liquidsoap-full-0.9.0/liquidsoap-0.9.0/doc' make[3]: Entering directory `/home/somebody/Desktop/liquidsoap-full-0.9.0/liquidsoap-0.9.0/doc/content' make[3]: Leaving directory `/home/somebody/Desktop/liquidsoap-full-0.9.0/liquidsoap-0.9.0/doc/content' make[3]: Entering directory `/home/somebody/Desktop/liquidsoap-full-0.9.0/liquidsoap-0.9.0/doc/liqi' make[4]: Entering directory `/home/somebody/Desktop/liquidsoap-full-0.9.0/liquidsoap-0.9.0/doc/liqi' make[4]: `liqi' is up to date. make[4]: Leaving directory `/home/somebody/Desktop/liquidsoap-full-0.9.0/liquidsoap-0.9.0/doc/liqi' make[3]: Leaving directory `/home/somebody/Desktop/liquidsoap-full-0.9.0/liquidsoap-0.9.0/doc/liqi' Converting content/advanced.txt to html/advanced.html... /bin/sh: line 1: 18999 Segmentation fault ../liqi/liqi -i ../content/advanced.txt -o ../html/advanced.html make[2]: *** [html/advanced.html] Error 139 make[2]: Leaving directory `/home/somebody/Desktop/liquidsoap-full-0.9.0/liquidsoap-0.9.0/doc' make[1]: *** [doc-install] Error 2 make[1]: Leaving directory `/home/somebody/Desktop/liquidsoap-full-0.9.0/liquidsoap-0.9.0' }}} {{{ $ gdb ./liquidsoap-0.9.0/doc/liqi/liqi GNU gdb 6.8 Copyright (C) 2008 Free Software Foundation, Inc.
