This is essentially a duplicate of PR target/10904, which will not be fixable
before the upcoming 3.4 release.
The short story is that the SPARC back-end has no means to enforce registers
alignment (for example, to make sure to allocate an even-numbered FP register
for a double value).
The workaround is to either declare 'ThumbnailSize' as an 'unsigned long' or to
turn 'ConvertAnyFormat' into a non-pure function (for example by making it
clobber a global variable).
