g++: ice 390 assert NULL

[Peter Schmid]

When I compile the following file with egcs-2.91.34 on an 
i386-pc-linux-gnulibc1 system the compilation crashes with an internal
compiler error. This did not happen with the previous egcs
snapshot. Changing NULL to 0 eliminates the problem.

save(const char* fname)

    datfile.open(fname,ios::out);
    assert(datfile!=NULL);
}
