This is split off from PR38474 for clarity. Compiling the testcase of that PR
(http://gcc.gnu.org/bugzilla/attachment.cgi?id=16873)
as
gfortran-4.3 -ffree-line-length-512 -g -ffree-form -ftime-report -c -O0
testcase.f90
requires about 20min in inline heuristics, estimating the stack frame size. It
also allocates 2.3Gb doing so.
