I suspect that it is related to me using dl() to load extensions (mysql,gd2,curl,sockets,mbstring)

Please try using the NTS version as you use FCGI. Be sure to have removed any DLL and extension from your path (or the old php.ini).

NTS seems to fix it.  so is it just that TS is buggy? or that FastCGI is not compatible with TS?
