c++ - 加载png文件时的Imagemagick问题

Question

我已经为 mac 编译了最新版本的 imagemagick，当我加载一个特定的 png 文件时，我得到了下面的断言。这有点麻烦，因为它会使程序在 Debug模式下崩溃。有人见过这个吗？有什么解决方法吗？

Assertion failed: (quantum_info->signature == MagickSignature), 
function DestroyQuantumInfo, file magick/quantum.c, line 215.

来自 "A Basic Introduction to PNG Features" - Integrity Checks -

PNG supports three main types of integrity-checking to help avoid problems with file transfers and the like. The first and simplest is the eight-byte magic signature at the beginning of every PNG image. It will detect the most common type of file corruption: that due to the transfer of a binary file in text. On most systems, line-endings in text files are flagged by either a carriage-return character (CR), a line-feed character (LF), or both. Macintoshes use CRs; Unix systems use LFs; and all non-Unix PC systems (DOS, Windows 3.x/95/NT, OS/2) use CR/LF pairs.
