Re: Undefined reference to TBP

[P C <pchwood at yahoo dot com>]

Thanks Tobias for confirming the bug.
I've filed bug 44064 and 44065
for the ICE when merging the two files and the linking problem when the two files aren't merged. I might've file just one, though since the root may be the same.

Cheers,
Pierre

I think the issue is not known and it occurs with the (almost) latest
4.6 build of today.
Thus: Please fill a bug report in Bugzilla.

By the way, if one puts both files into one, one does not get a
link-time error but a segfault:

hjf.f90:37:0: internal compiler error: Segmentation fault

(37 is the XXX line.) valgrind shows:
