Thanks for testing. I am unable to compile with the current unstable
package on debian wheezy, but I copied your file you emailed and it
compiles without the segfault [1]. I compile both the code you posted
and the "WebClient" example without any errors.
I forwarded the patch upstream to the original author of the arduino
library port to gcc 4.7. I can't see which version of gcc-avr you are
using, but segfaults sometimes fall as a problem with ld. For now, I
guess we can just make sure we have an updated toolchain and see if it
was some configuration error.
