int compiler error bootstrapping on openserver

int compiler error bootstrapping on openserver

[Robert Lipe]

OpenServer worked pretty well oh, about three days ago.  I just did
an update (and did another since seeing this just in case things were
wierded out temporarily) and a make.  I did another make just to be sure
this wasn't a fleeting (RAM error) problem.   It seems repeatable.

host==target==i486-pc-sco3.2v5.0.4

The make proceeds OK until we get to:

/home/play/negcs/gcc/xgcc -B/home/play/negcs/gcc/ -O2   -DIN_GCC    -g -O2 -Wall  -I./include   -g1  -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -fexceptions    -I. -I../../egcs/gcc -I../../egcs/gcc/config \
  -c ../../egcs/gcc/cp/tinfo.cc
../../egcs/gcc/cp/tinfo.cc: In method `void * __class_type_info::dcast(const class type_info &, int, void *, const class type_info * = 0, void * = 0) const':

include/typeinfo: At top level:

make[2]: *** [stmp-multilib-sub] Error 2
make[1]: *** [stmp-multilib] Error 1
make: *** [all-gcc] Error 2

I just did a 'cvs update' and resovled even the generated files
(configure, parse,etc.) against those in the tree and still get the
same.

I know we've seen some ICE's while building tinfo.cc before in quarters
past, but I really can't recall the details.

This isn't during the coff build, so it should be pretty close to the same
thing the linux crowd would be doing.    Are you guys seeing that fail?

OSR worked fine for me yesterday, but not a few hours ago.
I got an error requesting me to submit a bug report too, but didn't do so.
I think it was NOT the one you saw.

I've done a total refetch, and it barfs, pretty much like yours does:

Yep, same here on i586-linux-gnulibc1.

Same over here, after updating this morning (ca. 10:00 UTC), on  
m68k-next-nextstep3, so it's probably pretty generic:

Hope someone can make something out of this - it's C++, so my NIH  
alarm immediately closed down all relevant brain capacity ...
