0002082: Crash with \is_infinite
Using the built-in \is_infinite causes wp to crash. This is used in the provided libc specifications (math.h), and a call to these functions will cause a crash.

Please report as 'crash' at http://bts.frama-c.com/. Your Frama-C version is Neon-20140301. Note that a version and a backtrace alone often do not contain enough information to understand the bug.
