重新编译一下: configure --enable-debug=yes make clean make install 编译出debug版本,然后,再gdb test_button,如果程序异常终止,用back命令查看函数调用栈信息,把它复制出来。 貌似,在控制台模式不好复制gdb打印的内容。。。 可以试试用重定向,gdb test_button >test.txt 输入r+回车,程序异常终止后,再输入back+回车,然后再q+回车,y+回车,gdb打印的内容就重定向输入值test.txt文件了,把文件内容贴上来。
Sorry, something went wrong.
fix-> #7 LCUI退出时出现异常:memory corruption
ebdf6fa
当指定的字体路径无效时,LCUI会free掉一次FT库,而在LCUI程序退出时,又会对FT库进行free,导致段错误,现已解决。
刚刚在其它目录里创建了个新程序,由于指定的字体路径无效,会free掉一次FT库,而在LCUI程序退出时,又对FT库进行free,导致段错误。 现已解决,commit信息在此查看:ebdf6fa
