Re: Problem with alignment under Linux [SEC=UNCLASSIFIED]

Hi, Andrew!

Thanx for the quick answer.

yes, we are talking about 32bit binaries.

I was under the impression that it might have to do with the inclusion of the
union, which brings the trouble.

Can you give me a hint what to search for in the header files? I've been
looking for pragma, pack, alignment, 32 and 64, so far with no success. I
could also include the header files in my email, but I guess, you don't want
to go through more than 340 KBs of header files...

OK, I will fix this in the program.

What else can I do to support?

Thanx,
