I don't have this problem under Solaris 2.7 using gcc and Sun Workshop f77
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 ...
