Bash Version: 4.3
Patch Level: 27
Release Status: release

Description:
  This is a bug affecting the latest of the shellshock patches at the time of 
  writing, 4.3.27.  If bash is configured and built on a system with no 
  libtermcap, it attempts to build statically linking its own one.  In this 
  case, the resulting bash that is built does not correctly wrap long input 
  lines.

Repeat-By:
  ./configure while no libtermcap is available, or make the following changes
  to the configured makefile:
  
  < LDFLAGS =  $(STATIC_LD) $(LOCAL_LDFLAGS) $(PROFILE_FLAGS) $(CFLAGS)
  ---
  > LDFLAGS =  -L./lib/termcap $(STATIC_LD) $(LOCAL_LDFLAGS) $(PROFILE_FLAGS) 
$(CFLAGS)
  311c311
  < TERMCAP_LIB = -ltermcap
  ---
  > TERMCAP_LIB = ./lib/termcap/libtermcap.a
  314c314
  < TERMCAP_DEP =
  ---
  > TERMCAP_DEP = ./lib/termcap/libtermcap.a


Fix:
  Immediate workaround is to install libtermcap.  The bug appears to have been 
  introduced between patches 4.3.25 and 4.3.27.
