libgc4: broken on PowerPC

["C.M. Connelly" <c@eskimo.com>]

Package: libgc4
Version: 4.14-6
Severity: grave


I just filed a bug report against w3m (#57121), which uses libgc4,
but rumor has it that the problem is actually with libgc4, which
is apparently broken on PowerPC.

Basically, w3m segfaults on startup:

   diziet% w3m
   Segmentation fault
   diziet% 

Running gdb on w3m-en gets you

   diziet% gdb w3m-en

I've tried downloading the source package for w3m and compiling
that, but I run into major problems with a missing gc.h.  There is
no libgc4-dev package available for PowerPC (although it is listed
in the database).  When trying to download it, I get

   diziet:/usr/src/w3m-0.1.6# apt-get install libgc4-dev
   Reading Package Lists... Done
   Building Dependency Tree... Done
   Package libgc4-dev has no available version, but exists in the database.
   This typically means that the package was mentioned in a dependency and 
   never uploaded, has been obsoleted or is not available with the contents 
   of sources.list
   E: Package libgc4-dev has no installation candidate

I hope that's enough to get you started.  If you need more
information, please ask -- I'm more than willing to install other
software that uses libgc4 to gather more data.

Thanks!
