[fpc-pascal] ImageMagick and Static Linking

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, -- Andrew Brunner Aurawin LLC 15843 Garrison Circle Austin, TX 78717 https://aurawin.com Au

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 +++ b/rtl/i386/i386.inc @@ -1523,7 +1523,7 @@ movl(%eax),%edx subl$8,%edx // [102] If l^<0 then exit;

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 fpc_AnsiStr_D

Re: [fpc-pascal] FPC 2.6.2 throws SEGV in fpc_AnsiStr_Decr_Ref(). How is this possible?

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. Bruce. On Wed, May 8, 2013 at 11:49 PM, Jonas Maebe wrote: > > On
