Jurij Smakov found the cause of the bug, as recorded in the Debian bug log.  Apparently, the test in config/config.align.c for testing whether the architecture needs shorts/ints to be word-aligned does not work properly, as gcc optimizes away the assignments that are used to test it if "-O2" is part of CFLAGS (which it is by default).

A fix is to force the compiler to make the assignments by, for example, passing buf to an external function.  For example, the attached file (just a 3-line change from the original config/config.align.c) does this by passing buf to puts.

(This is Debian bug #362192 -- http://bugs.debian.org/362192)

When building gorm.app on the Debian autobuilders, autogsdoc exits with a Bus error on the sparc and hppa architectures:

echo '@set GNUSTEP-VERSION' 0.10.0 \
> version.texi
echo '@set GNUSTEP-GCC 2.95.0' \
>> version.texi
echo '@set GORM-VERSION 1.0.6' \
>> version.texi
autogsdoc -MakeFrames YES \
  -DocumentationDirectory InterfaceBuilder \
  -Declared InterfaceBuilder \
  ../GormLib/*.h 2> /dev/null
/bin/sh: line 3: 13066 Bus error               autogsdoc -MakeFrames YES -DocumentationDirectory InterfaceBuilder -Declared InterfaceBuilder ../GormLib/*.h 2>/dev/null
make[1]: * [before-all] Error 138
make[1]: Leaving directory `/build/buildd/gorm.app-1.0.6/Documentation'

The other architectures seem to be fine.  (The version of GNUstep Base currently in Debian is 1.11.2.)
