System name: hodge
Type and version: KN01 7.6G (1 update(s) to same version)
Display type: PMAX-MFB
What were you trying to do?
Run codecenter on a program which includes <alloca.h>.
But that's not important.
What is important is that <alloca.h> under ULTRIX defines
alloca to be __builtin_alloca. It does nothing else.
What's wrong:
; cat foo.c
main () { __builtin_alloca (0); }
; cc foo.c
Fatal error in: /usr/lib/cmplrs/cc/ugen Trace/BPT trap - core dumped
;
This happens with arguments other than 0 as well.
I just like typing the character `0'.
What should have happened:
There should be no core dumping or toad sexing.
Please describe any relevant documentation references:
alloca(3)
