I confirm that both bugs are still there at revision 124c48df1aab.
inifite_loop.py really looks like an unroll bug.
str_instead_of_token is weird. If I run it with pypy 1.7, I get a Fatal RPython
error: BytecodeCorruption even with --jit off
with pypy 1.8 and trunk, I get the applevel exception the user reported; if I
disable unrolling, I get this:
$ pypy-c --jit enable_opts=intbounds:rewrite:virtualize:string:heap
File "jit_metainterp_optimizeopt___init__.c", line 271, in optimize_trace
File "jit_metainterp_optimizeopt_optimizer.c", line 3596, in
File "jit_metainterp_optimizeopt_heap.c", line 3694, in OptHeap_emit_operation
File "jit_metainterp_optimizeopt_heap.c", line 4131, in OptHeap_emitting_operation
Fatal RPython error: AssertionError
so it's possible that it's not an unroll fault, but that unroll simply gets a
list of operations which is "buggy".
