Hello !
zend_dtrace_gen.h is generated during configure using dtrace -h and then
the object file is generated using dtrace -G on Solaris and FreeBSD (mac
os doesn't need a compiled object files of the probe description). On
FreeBSD dtrace -h fails because of a syntax error in a dtrace script
that comes with the OS, therefore the dtrace headers cannot be
generated. We need to generate the headers as every OS generates
different DTrace headers.
I can now compile php on Freebsd 8p3 without any problem.
But when i'm using dtrace with php, dtrace segfault with a core.
f...@witchblade:/usr/home/fch/php/sapi/cli
26> sudo dtrace -ln 'php*:::' -c './php -m'

Segmentation fault: 11 (core dumped)
dtrace work fine with DTraceToolkit.
The gdb backtrace say :
