#432 SIGSEGV in aspell

[Zane U. Ji]

Use mingw build x86_64-4.9.1-release-posix-seh-rt_v3-rev2.7z to build Aspell 0.60.6.1:

./configure --prefix=/mingw/x86_64-w64-mingw32 && make install

Then compile the following program (testaspell.c):

#include <stdio.h>
#include <aspell.h>

int main()
{
    aspell_reset_cache(NULL);
    return 0;
}

with:

gcc testaspell.c -laspell -o testaspell.exe

Debug it with gdb:

(gdb) r

Everything was fine when using gcc 4.8.2.

I'm test on MSYS2 with our mingw-w64 toolchains (GCC 4.9.2) and aspell packages. Everything is ok for me.

Alexey.
