--- Comment #12 from janus at gcc dot gnu.org 2011-08-30 17:09:22 UTC --- (In reply to comment #11) > And indeed it seems to fix the segfault. ... and regtests cleanly. Unfortunately, there is one more complication: When compiling the two files from comment #1 one after the other, one gets a linker error: > gfortran-4.7 -c module.f90 > gfortran-4.7 program.f90 /tmp/ccU0pMIF.o: In function `MAIN__': program.f90:(.text+0x16): undefined reference to `__g_nodes_MOD___vtab_g_nodes_T0' program.f90:(.text+0x87): undefined reference to `__g_nodes_MOD___vtab_g_nodes_T1' Note: This seems to happen with trunk and 4.6, while it works with 4.5. I was hoping we had gotten rid of those for good (cf. e.g. PR44065 and PR45674).
