[Bug c++/33075] New: (mingw) Dwarf2-EH causes stack leak with VLA

["darkxun at paran dot com" <gcc-bugzilla at gcc dot gnu dot org>]

On GCC-3.4.5 for mingw with Dwarf2-EH
Configured with: ../gcc-3.4.5/configure --with-gcc --with-gnu-ld --with-gnu-as
--host=mingw32 --target=mingw32 --prefix=/mingw --enable-threads --disable-nls
--enable-languages=c,c++,objc,f77 --disable-win32-registry --disable-shared
--disable-sjlj-exceptions --enable-libstdcxx-debug
Thread model: win32
gcc version 3.4.5 (mingw special)

The following testcase shows the stack grows every time an exception get
handled
until the program runs out of stack and crashs.

----------------------------------------
#include <stdio.h>

int main()
{
    while(1)
    {
        try {
            int n = 8*1024;
            int p[n];
            fprintf(stderr, "p=%p\n", p);
            throw 1;
        }catch(...) {
        }
    }
}
