Description:

Compile warnings in gd.c show that that the return value logic for
imageaffinematrixget is wrong:

/home/cjones/php-5.5/ext/gd/libgd/gd.c: In function
‘gdImagePaletteToTrueColor’:
/home/cjones/php-5.5/ext/gd/libgd/gd.c:3014: warning: unused variable
‘alloc_y’
/home/cjones/php-5.5/ext/gd/gd.c: In function
