BMessage::PrintToStream crashes on Int8

[MrSunshine]

#include <stdio.h> 
#include <app/Message.h> 
#include <support/DataIO.h> 
#include <string.h> 
 
int main() { 
        BMessage msg; 
 
        msg.AddInt8("testing", 8); 
 
        msg.PrintToStream(); 
 
        return 0; 
} 

crashes for me with latest rev of haiku hrev36029 Works fine with Int16 or Int32 tho

Gcc 4 hybrid, I presume ?

I fixed a similar bug some time ago, btw.. can't find the ticket.

[jackburton]

Oh, btw... backtrace would be useful :)

[humdinger]

I see that too, with gcc4hybrid. Backtrace:

That looks exactly like the one I fixed. Are you both sure you upgraded Haiku correctly ?

[humdinger]

I always build my images directly to a partition, overwriting /boot. I then play back a zipped archive of ~/home. So, as long as there's nothing changed with some setting there, it should be OK.
Have you tested the above code? Does it work for you?

Replying to humdinger:

Not yet, since I don't have access to my development machine.

[jackburton]

It's #5596, btw.

[jackburton]

It's fixed in hrev36052.
