sdl2.0.8 crashes with software rasterizer about pascal-sdl-2-headers HOT 10 CLOSED

i just rebuild sdl2 without sse , it works now
seems problem of alignement between gcc&sse and fpc

from pascal-sdl-2-headers.

FPC user manual says that runtime error 216 is an Access Violation. This usually means referencing an invalid pointer. Can you add NIL-checks to see if SDL_CreateWindow and SDL_CreateRenderer calls do not fail?

Also, you can use a triple backtick ("```") to put a code block in a comment; this makes it easier to read such stuff. :)

Ah, right. There seems to be a bug in FPC currently where sometimes it produces bad alignments.

@suve got any link to the FPC bugtracker?

from pascal-sdl-2-headers.

We've noticed a breakage on Fedora, where some FPC-compiled programs would crash with an Access Violation during cleanup (somewhere in glibc destructors). This was deemed to be caused by some misaligned data. Here's the link to the Red Hat Bugzilla ticket: 1526848

To be fair, I haven't checked if anyone reported this upstream. I'll look into that tomorrow.

i tried with fpc 3.1.1 (trunk ), and seems there is no problem !!
the problem was with fpc 3.0.0 and 3.0.4
no need to fill a report :)

from pascal-sdl-2-headers.

the problem raised again :( , even with fpc trunk
this time with the function SDL_RenderFillRect .

from pascal-sdl-2-headers.

is it still happening with updated fpc/lazarus?

from pascal-sdl-2-headers.

the last time i tried with fpc trunk Feb 16 , yes it happend
but since sdl2.0.8 is officially released , i download the library's binary yesterday and seems no problem , but maybe they build it without sse !!

from pascal-sdl-2-headers.

i'm closing this issue then, as I don't think this is an issue with the headers itself, but rather fpc. Feel free to keep us updated here, though.
