mingw 编译c++ 最简单的程序出现Program received signal SIGSEGV, Segmentation fault.

现象是基本程序

#include <iostream>#include <stdio.h>#include "time.h"#include "receive.h"void receive::recv(void){time_t t1;time(&t1);std::cout << "current time" <<ctime(&t1)<<std::endl;//printf("hello o\n");return;}

Makefile是这样的

platform = $(shell uname)#ifneq (,$(findstring MINGW,$(platform)))CXXFLAGS = -I$(QTDIR)/include -I$(QTDIR)/include/QtCore -I$(QTDIR)/include/QtGui -I. LDFLAGS =  -Wl,--enable-runtime-pseudo-reloc  -L$(QTDIR)/libQTLDLIBS =  ${LDFLAGS} -lQtCore4 -lQtGui4 -lSetupApi -lregex MOC = $(QTDIR)/bin/mocelseCXXFLAGS = $(shell pkg-config --cflags QtCore QtGui 2>/dev/null) -Wall -O0QTLDLIBS = $(shell pkg-config --libs QtCore QtGui 2>/dev/null)MOC = $(shell pkg-config --variable=moc_location QtCore)LDLIBS +=  -ldlLUAPLATFORM = linuxendifLDLIBS += $(QTLDLIBS)TARGET = no1OBJS = no1.o receive.oall:$(OBJS) g++ -flto $(CXXFLAGS) $^ $(LDLIBS) -o $(TARGET)#all:$(OBJS)#g++ -Wl,--enable-runtime-pseudo-reloc -o ../$(TARGET) $^ ${LDFLAGS} -L/usr/lib/qt3/lib -L/usr/X11R6/lib -lQtCore4 -lQtGui4%.o:%.cppg++ -pipe -Wall -W -O0 -DQT_NO_DEBUG ${CXXFLAGS} -c $<.PHONY:all cleanclean:-rm -rf *.o *.exe $(TARGET)

编译结果正常，可是运行的时候出现段错误。

找了很久都没有答案，有些论坛上说是BUG，我不太相信，

后面继续找，终于找到答案了。

就是不知道是什么原因。

mingw-w64编译的程序,

需要使用的dll有libgcc_s_dw2-1.dll,libstdc++-6.dll,libwinpthread-1.dll 具体作用不清楚.如果没有程序运行会出现异常.
