seg fault in zif_current

[michbsd]

Hi,

xhprof: 0.9.4 php: 5.6 OS: FreeBSD 10.x

After the "xhprof_enable(XHPROF_FLAGS_CPU | XHPROF_FLAGS_MEMORY);" - I get SIGSEGV (signal)

Attaching a debugger (unfortunately without symbols) I see:

Program received signal SIGSEGV, Segmentation fault.

Not quite sure if this is a known issue?

thanks,

Setting XHPROF_FLAGS_NO_BUILTINS is solving the issue...

Could this be it : https://github.com/phacility/xhprof/commit/55a47c0d8ffeea4b84133fd21103caa816676b5d
