We have newly installed gcc-2.2.2 on a SPARCstation using SUNOS 4.1.
It seems to me, that a "hard bug" still remains.

Look at the following example. I expect an output of
    isA: 3 3 3 3
but get:
    isA: 3 3 3 2

Could you pleace respond, if it is a known bug and if you will fix it.
Thank you,

Roland.
