pngcairo terminal error

[grimper]

Hello all,

After setting the terminal to pngcairo, trying to plot a sin(x) or just type "test" gave me a error message like this:

>gnuplot(20208) malloc: *** error for object 0x3: Non-aligned pointer being freed
>*** set a breakpoint in malloc_error_break to debug
>Bus error

I am using gnuplot 4.5, under mac os 10.5.8.
It seems to be a problem from cairo. Since I also tried the terminal pdfcairo, after typing "test" , it shows:

>Floating point exception

Does anyone has an idea ?

Thanks a lot,

Zong
