Output from "gfortran -v -fplugin=/usr/local/lib/dragonegg.so -c strtri.f"
I'm getting a segfault when I try to build the strtri.f file from LAPACK
(cf. http://www.netlib.org/lapack/explore-html/de/d76/strtri_8f_source.html)
using the trunk build of LLVM + DragonEgg (r140178) on
x86_64-linux-gnu. There's no problem when I run gfortran by itself:
$ gfortran --version | head -1
GNU Fortran (Ubuntu/Linaro 4.5.2-8ubuntu4) 4.5.2
$ gfortran -c strtri.f
However, badness happens when I toss in the DragonEgg plugin:
$ gfortran -fplugin=/usr/local/lib/dragonegg.so -c strtri.f
