Environment: 4.2bsd on a VAX.
I had adb coredump on me! It seems to be repeatable (this is of course
not how it happened the first time):
% adb
00008000=f
Floating exception (core dumped)
%
It's pretty obvious to anyone who knows VAX floating-point format what
is going wrong. That value is a floating reserved operand. But the
last thing adb should do is coredump over it (or over anything for that
matter)! I expect a message; perhaps something like "(reserved
operand)" instead of the floating-point value.
I also had lex coredump on me. I had a file `x' and a file `x.lex'; by
mistake I said `lex x' rather than `lex x.lex'. Lex coredumped!
Again, I would expect error messages (lots of them). Here it is, done
deliberately:
% lex << FOO
/* note that // gets turned into /* and */ by comcon
/**/
int variable; // comment
FOO
Segmentation fault (core dumped)
%
Unfortunately /usr/bin/lex is stripped so I have no idea where it is
dying.
Oh well. Perhaps someday I will even have fixes for these (not this
time though).
