1189 * FindExecutable() segfaults. The buffer must be of size at

1193 * A value greater than 32 on success, less than or equal to 32 otherwise.

1196 * NOTES
1197 * On Windows XP and 2003, FindExecutable() seems to first convert the

1199 * characters of the extension, and expects to find an association for those.
1200 * However other Windows versions behave sanely.
