#1100: Correct backtrace generation in Carpet
 Reporter:  eschnett  |       Owner:  eschnett
     Type:  defect    |      Status:  new     
 Priority:  major     |   Milestone:          
Component:  Carpet    |     Version:          
 Keywords:            |  
 The file backtrace.cc in CarpetLib does not #include <cctk.h>; hence all
 HAVE_BACKTRACE* macros are undefined, and only basic backtraces are

 Correcting this is non-trivial, since the backtrace code is arcane, is
 written in C, probably expects glibc, contains (I'm fairly certain) memory
 allocation errors, and doesn't build e.g. on Mac OSX. The code also spends
 an inordinate amount of time allocating and freeing string buffers, which
 should be replaced by simply using C++ streams.

 The backtrace code also probably requires a few more autoconf tests, so
 that it can be disabled where it does not work.
