Question

我有一个使用xerces 3.2.1的应用程序。在Sun C ++ 5.8上一切正常。我们正在使用最新的编译器Sun Studio 12.6，C ++ 5.15。我编译了xerces和我的应用程序。一切顺利。当我从应用程序运行并引发异常时，它不会陷入xerces中，并且应用程序崩溃。没有任何代码更改可用于旧编译器。看起来在抛出异常之后，堆栈不会展开。这就是我得到的-

在链接和运行时，应用程序和xerces都使用正确的库。不知道出什么问题了。 xerces使用以下代码进行编译-

./configure CC=/opt/developerstudio12.6/bin/cc CXX=/opt/developerstudio12.6/bin/CC  CFLAGS="-O -m32"  CXXFLAGS="-O -m32 -std=c++11" LDFLAGS="-std=c++11 -L/opt/developerstudio12.6/lib/compilers/CC-gcc/lib"

所用应用程序的相同选项。

像这样抛出异常-

ThrowXML(ParseException,XMLExcepts::NoError);

class ParseException : public XMLException

代码看起来不错，因为它可以与旧的编译器一起使用。与C ++ 11选项有关吗？有什么可以尝试的吗？

编辑：LD_PRELOAD=/opt/developerstudio12.6/lib/compilers/CC-gcc/lib/libgcc_s.so.1 如某些帖子所述，但没有用。

异常会导致应用程序崩溃，并且无法被Sun Studio C ++编译的应用程序捕获
