[PyPy-issue] [issue529] Overflow detection fail with JIT

[Armin Rigo]

Armin Rigo <arigo+pypyissues at codespeak.net> added the comment:

Found the reason.  It's because some setfield_gc are inserted between
int_xxx_ovf and guard_no_overflow, and the setfield_gc does a 'TEST' related to
the write barrier.
