Hello, I am trying to get the excellent Heirloom troff[1] running on OpenBSD. It compiles and installs fine. However, running the compiled troff results in random segmentation faults; sometimes it works, most of the time it does not.
I contacted the author (G. Ritter) who suggested to compile the program with the debug flag (-g), and to subsequently run it in gdb. I did that, but not being a developer, the output did not tell me anything useful. Anyway, here is the output I got: ------------------ cut here -------------------- $ gdb /opt/ucb/troff GNU gdb 6.3 Copyright 2004 Free Software Foundation, Inc.

Something else that might be related (from the README): ------------------ cut here -------------------- The locale-dependent character input in troff assumes that the C library represents wchar_t values as Unicode characters. This is the case on any modern Unix system. ------------------ cut here -------------------- Has anybody been able to successfully run Heirloom troff on OpenBSD? And, if yes, how to enable support for UTF-8 input files? Thanks for any hint. Dirk
