Re: [eigen] Problem with ei_cache_friendly_product?

[FMDSPAM <fmdspam@xxxxxxxxx>]

Hi Benoit,

The situation is even more wired. The crash not only depends on the code 
it self and if release or debug.
It also depend on the calling environment.
Started below MSVC some test run throught w/o problems but do crash when 
started by command prompt.
See my protocol below

A) Original testcase "Matrix<double,16,16>": started in MSVC or from 
Command promt:
CacheFriendlyProduct.h:
202:    PacketType A0, A1, A2, A3, A4, A5;
+++:    std::cout << "k: " << k << ", addr: " << localB + k*MaxBlockRows 
<< std::endl;
203:    A0 = ei_pload(localB + k*MaxBlockRows);

gives me
at first (caused by "line b)" of my testcase):
k: 0, addr: 003214D0
.... (many lines skipped, see out.txt)
k: 14, addr: 00321C50
(do all end with 0 => no alignment issue)

but then (caused by "line d)" of my testcase):
k: 0, addr: 00126FE8
(do not end with 0 => alignment issue)

B.1) Your suggestion test case: "MatrixXd" started from MSVC:
everthing is fine, no crash at all.

B.2) Your suggestion test case: "MatrixXd" started command prompt:
gives me: "k: 0, addr: 00187F58" at the very first time ( "line b)" )
and consequently crash.

Unfortunately, most of the inner details of your code is beyond my 
knowledge, but i will run test cases whenever you told me to do  :-) .

Maybe something of my setup is broken?
Could please another MSVC-User run my testcase?

Cheers and merry christmas, Joyeux Noël
Frank
