When running the ABC attached, I get an assertion failure:

It's a nanojit bug: when running with -Dinterp, it works.

The patches of bug 607816 fix this issue, so it appears to be the same root cause. But double checking prior to marking this a dup.

# The following snip-it highlights the issue and was generated by
# running a debug debugger version of tamarin with following
# flags: -Dverbose=verify,jit,raw,regs
#
# NOTE due to 'raw' option the code is displayed in reverse order.
# i.e. instructions are displayed from physically higher addresses
# to lower addresses.
#
# Looking at the trace below notice how csn is used in B52 (i.e. parameter of callv)
# and since control flow from the prior block appears to fall into B52, the
# allocator is restoring it along that edge; i.e. lea ecx,-236(ebp) <= restore csn
#
# This is incorrect since the call to throwAtom from the prior block never
# returns and thus there is no fall-through path into B52 or put another
# way; we shouldn't have love from that shack.
#
debugExit1 = callv.all #debugExit ( parami1 csn )
