[Bug fortran/45659] LTO / function pointers with iso_c_binding

[Joost dot VandeVondele at pci dot uzh dot ch]

A slight variation leads to an lto1 ICE:

declaring build eri as: 'extern void (*build_eri)(void);'

leads to:

> gcc -c -flto test_c.c ; gfortran -c -flto test.f90 ; rm all.a ; ar -r all.a test_c.o test.o ; gfortran -fuse-linker-plugin -flto -O3 all.a
ar: creating all.a
lto1: internal compiler error: in lto_varpool_replace_node, at lto-symtab.c:292
Please submit a full bug report,
with preprocessed source if appropriate.
