well, I tried a bunch of tests this this afternoon and I couldn't get
anything to fail with SIGILLs or anything like that. could you guys
give some more details on exactly what goes wrong and what the machine
is doing when it happens?
building mozilla dies pretty early with:
cc -o prprf.o -c -I/usr/X11R6/include/gdk-pixbuf-1.0 -I/usr/pkg/include -I/usr/X11R6/include -O2 -pipe -I/usr/pkg/include -I/usr/X11R6/include -pipe -ansi -Wall -pthread -O2 -fPIC -DPIC -UDEBUG -DMOZILLA_CLIENT=1 -DNDEBUG=1 -DXP_UNIX=1 -DNETBSD=1 -DHAVE_BSD_FLOCK=1 -DHAVE_LCHOWN=1 -DHAVE_STRERROR=1 -D_REENTRANT=1 -D_THREAD_SAFE=1 -DFORCE_PR_LOG -D_PR_PTHREADS -UHAVE_CVAR_BUILT_ON_SEM -D_NSPR_BUILD_ -I/build/pkgsrc/www/mozilla/work/mozilla/dist/include/nspr -I../../../pr/include -I../../../pr/include/private prprf.c
prprf.c: In function `BuildArgArray':
prprf.c:620: error: incompatible types in assignment
the failing line is:
and at the top there is:
** Note: on some platforms va_list is defined as an array,
** and requires array notation.
#if (defined(LINUX) && defined(__powerpc__)) || \
(defined(LINUX) && defined(__s390__)) || \

#define VARARGS_ASSIGN(foo, bar) foo = bar
#define VARARGS_ASSIGN(foo, bar) (foo) = (bar)
looks like mozilla needs to be updated for gcc 3.3.1.
well, looks like it should really just be using va_copy().
