#687: conc049 <<loop>> with heap profiling turned on

    Priority:  normal    |    Milestone:  6.4.2  
   Component:  Compiler  |      Version:  6.4.1

While trying to fix #492, I noticed:

 {{{
 > ./conc049 +RTS -hc
 conc049: <<loop>>

 conc049: <<loop>>

 conc049: <<loop>>

 conc049: <<loop>>

 conc049: thread blocked indefinitely
 }}}

 but the program works as expected without +RTS -hc, even if compiled for
 profiling.
