ImageMagick: MSL image stack index may fail to refresh, leading to leaked images
Sometimes msl.c fails to update the stack index, so an image is stored in the wrong slot and never freed on error, causing leaks.

Direct leak of 13512 byte(s) in 1 object(s) allocated from:
#0 0x7ff330759887 in __interceptor_malloc ../../../../src/libsanitizer/asan/asan_malloc_linux.cpp:145
