Bug 23260

Thanks for the bug report.

Does MSYS/mingw have posix_memalign()? Ie., does this work:

   #include <stdlib.h>

   int main ()
   { 
       void *p;

       posix_memalign (&p, 16, 2343);
   }

?

It's not got that either - grep -r "memalloc" mingw/include doesn't find anything :(

There is something called _aligned_malloc or some such inside MSVCRT70.DLL and higher, which I assume would make the test work - although that's not technically a system DLL, it's on most Windows systems. I didn't feel like messing around trying to make that work ..

A patch

Here is a patch that uses posix_memalign(), but falls back to malloc() if that is not available.

If you can test it on mingw, I'd appreciated it.

Thanks,

is a tarball with that patch applied.

The test compiles and succeeds.
Thanks for looking at this so quickly!
