Parachute?

What is the difference between a normal Segmentation Fault error and this
one?

 Fatal signal: Segmentation Fault (SDL Parachute Deployed)

What is “SDL parachute”? It can help me find where my errors are?

Thanks for any explanation…

Enzo.

 Fatal signal: Segmentation Fault (SDL Parachute Deployed)

What is “SDL parachute”? It can help me find where my errors are?

Your program (or the backend, or whatever) had a segfault, but the SDL
installs the “SDL parachute” as a signal handler for various fatal
signals, including SEGV (not necessarily fatal, but I’m guessing that the
SDL front end doesn’t have enough info to handle it in a clean way.)

If you need the normal signal behavior (ie, you want a core dump for
debugging purposes), you can do what I do: edit src/SDL_fatal.c, comment
out the SEGV in the fatal_signals array in SDL_InstallParachute, and
recompile.On Wed, 22 Sep 1999, Enzo wrote:

It’s actually even easier than that. After you call SDL_Init(), just
do: signal(SIGSEGV, SIG_DFL);

If you set your own signal handler for SIGSEGV, SDL will respect it,
and not install it’s own.

BTW, as far as I know, core files are useless for debugging multi-threaded
programs. Also, if you are running your program in a dangerous mode, i.e.
directly accessing the hardware under DGA or some such, then the default
behavior of dumping core and exiting will lock up your console.

When debugging these kinds of applications, I usually just telnet in from
another box and run the program under gdb.

Good luck!

Hi,

Sorry to be a bother. I didn’t get any mail from the list for about 8 days,
so I’m checking if it’s still working.

Me either. I was starting to think everyone moved to a newsgroup without
notifying the list. But then I remembered school just started and some
big game development projects are coming in for the home stretch :wink:

Actually, the last post I have with any mention to the newsgroup is this
from 09/19:******

Ok, I saw the SDL mailing list subscription messages for the newserver,
so any message sent to the mailing list ends up on the newsserver.
right? Does any message sent to the newserver also go the mailing list?

Yup. I’ll announce it officially on Monday. :slight_smile:


Shouldn’t there be some message on the
http://www.devolution.com/~slouken/SDL/ site? Oh, well. Thanks for the
info.

I thought the list and newgroup were cross sending messages between each
other so we didn’t have to use the newsgroup if we didn’t want to.On Fri, 1 Oct 1999, M. R. Brown wrote:

Hi,

I’ve been getting mail from this list over the past few days. It’s most
always synced up with the newsgroup too.
