I'm trying to get andrew to compile here, and I seem to be having a
problem with dynamic loading in atk--that is, ez works fine, but help
and zip don't. The symptoms are a core dump from an illegal
instruction. I don't have the version of gdb mentioned that
understands about dynamic loading (where can I get it?); without that,
I can't tell too much about the problem. trace(1) shows runapp
loading in the proper object files, and a backtrace from the core dump
shows several stack frames in the 0xff... range that seem to be from a
dynamically loaded module--they're after etext, so it seems like the
load is at least partially working.
The only unusual things about our setup are that we're
running AFS 3.0 and we're trying to build just about everything.
Has anybody seen this before? Does anybody have any ideas for
debugging it?
Sun 4/110, SunOS 4.0.3, andrew patchlevel 5
I fixed two Imakefiles so that they required librauth.a only when
AFS30_ENV was not defined, and changed the Imakefile in
.../atk/console/cmd to undefine AFS_ENV, since libcont.a didn't come
with AFS 3.0; I don't think either of these changes could have caused
this problem.
A backtrace from a core dump from help follows:
(gdb) run
