[erlang-bugs] Freeze in re:run

[Miroslav Urbanek]

Hi Eric,

thanks for your investigation. One thing I tried before is to
uncomment the line

#define ERLANG_DEBUG 1

in erts/emulator/pcre/pcre_exec.c. I don't have the output anymore,
but it clearly showed "heartbeat" message near "Loop limit break
detected". I think PCRE library doesn't properly return control to the
VM, but my understanding of Erlang and PCRE internals is rather
limited to see why.
