This is very likely the same trouble that I just spent some time
analyzing with Vin Everett on Sparc Linux (RedHat 6.0). We traced it
to something that looks suspiciously like a compiler error. I actually
considered asking around if anyone used same egcs version on Solaris,
but though "nah, probably not"....
Doug, could you
- recompile eigen.o with -g
- run it with -d gdb
- see if the crash resembles the one below
