C Language design: "core dump" and message "bus error"

[chkv]

I had a cord which HP_UX send error message and core dump, but under AIX and Windows both OK. WHY?

*va_arg(arglist,int*)=atoi(str+idx2);

Shalom,

Perhaps you can provide a little detail on what your expected results are.

It is possible this is generated by bad code, or perhaps the C compiler needs patching and update.

You didn't mention your OS version and compiler version.

Also, you shouldn't write tricky vararg code like this. You should use it as little as possible and only in simple operations:
int *pint = va_arg(arglist,int*);
*pint = atoi(str+idx2);

I assume you have followed all the rules of using stdarg(5) by doing:
void foo(const char *format, ...) {
    va_list arglist;
    va_start(arglist, format);
