Hello.
I want add access to AT-SPI interface.

Does it exist a pascal header for that ?
Does anybody know how to do it, via fpc, not lcl ?
Thanks.
Toc, toc, toc, is there anybody here ?

Thanks Jonas, that confirms what I suspected. Next time I trap an instance
of this (rare) fault I will inspect exactly which CPU instruction raised
the SEGV inside fpc_AnsiStr_Decr_Ref in search of a source of memory
corruption.

Michael, thanks for your feedback.
One thing that confuses me in light of Jonas' reply, if what you say is
correct (that local variables that have just come into scope are not
guaranteed to be nil) then assignment of Result := ''; at the first line of
foo may arbitrarily SEGV because
I've not managed to trap it again, but based on the information I have from
the last time it occurred I can say the error happened here:
--- a/rtl/i386/i386.inc

@@ -1523,7 +1523,7 @@
movl(%eax),%edx
subl$8,%edx
// [102] If l^0 then exit;
So here's some more diagnostic at the point of the SEGV:

Image Magick comes with static libraries and dynamic libraries.
Is there any way to make ImageMagick unit support the *.lib files?
I'm trying to avoid having to distribute the ImageMagick dlls.
Thanks,
