The issue is very complex, it depends on many factors (FreeBSD version, calling program, extensions loaded, ports options, etc.). In short words, dlopening and dlclosing libthr is bad. The final and definitive solution would be a libc including libthr (if I'm not wrong there was a plan to do it). A less drastic solution would be to link to libthr every program that dlopen() uncontrolled libraries (i.e. apache, php, etc.). I've already proposed this change, but was considered too risky at that time. So, for now, you have to live with the LINKTHR php option that does its best to make all happy. -- Alex Dupre
