Comment:
I did reproduce this with 7.4.1, but could not reproduce it with 7.4.2. I
think it may be a symptom of the bug I fixed in this commit:
commit 20906163a6aee2b76de240c4171928f83a5d9077

Fix a bug in threadStackOverflow() (maybe #5214)
If we overflow the current stack chunk and copy its entire contents
into the next stack chunk, we could end up with two UNDERFLOW_FRAMEs.
We had a special case to catch this in the case when the old stack
chunk was the last one (ending in STOP_FRAME), but it went wrong for
other chunks.
I found this bug while poking around in the core dump attached to
options and running the nofib suite: imaginary/wheel_sieve2 crashed
with +RTS -kc600 -kb300.
I don't know if this is the cause of all the symptoms reported in
