[x264-devel] Crash with x264 r1460

First I get lots of error in help message.
Next I found that x264_param is not initialize.

I add x264_param_default( &param ); before Parse command line
And next I use these arguments.

I use fprofiled  and the build is completed.

But when use the following arguments.
--profile high --preset veryslow --rc-lookahead 250 --crf 18
I get a crash.

Build again without fprofiled get the same result.

configure result is the following with gcc version 4.3.4 (Gentoo 4.3.4 p1.0,
pie-10.1.5)

Platform:   X86_64
System:     LINUX
asm:        yes
avs input:  no
lavf input: yes
ffms input: no
mp4 output: yes
pthread:    yes
debug:      no
gprof:      no
PIC:        no
shared:     no
visualize:  no

And the gdb backtrace is the following

(gdb) backtrace
