PR 36044 ( is an enhancement 
request for a way to display backtraces from user code. I'm against adding yet 
another nonstandard intrinsic for this purpose (which is how Intel Fortran does 
it), but I would like to offer the following solution to the issue, as I think 
it can be useful in some cases (and the way I suggest should not be a 
maintainance burden for us):

  -- export _gfortran_show_backtrace() from libgfortran (instead of it being an 
internal function)
  -- add documentation on how to call this function from user-code using BIND(C)

Patch was bootstrapped and regtested on x86_64-apple-darwin11, also tested with 
"make info html pdf". OK for trunk?
