Comment (by alpmestan):

 I'm seeing a failure for `profasm` as well with a recent checkout of the
 master branch (commit 8b823f270e), with the simplifier tick limit error.
 If we increase the limit, we run out of stack space. If we increase the
 stack size enough with -K, we run out of simplifier ticks again. I'll mark
 the test as expected broken with the `profasm` way, but this does look
 rather suspicious.
