In fact the gfortran frontend makes it through the fft257.f90 test case in a few seconds. The memory hogging and cycling is happening in middle-end. With a simple variation of the patch in comment #5, I am able to achieve the 2.5 second compilation with only one regression. I am not sure there is a way to discern the difference between the fft257.f90 and array_constructor_20.f90. The difference being one has the initialization has a parameter and the other not. I plan to explore further and report back here. -- jvdelisle at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|RESOLVED |UNCONFIRMED Keywords|ice-on-valid-code |compile-time-hog Resolution|DUPLICATE | Summary|Endless loop when compiling |Endless loop when compiling | |- middle-end? http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32489
