ilnumerics - Linear equation solving leads to program exit (x64) -

i have problem linear equation solving. have 2 matrices: , b. dimension of scheme 24 ("a" 24x24 matrix). phone call "ilmath.linsolve(a, b)", programme closing unexpectedly without exceptions or messages. have found problem nowadays platform target x64 , absent x86. can comment this? bug or misunderstanding of ilnumerics usage?

os windows 7 (64 bit) on intel core i7.

below matrices result error (can't find how attach files). on x86 platform result nan, acceptable (as opposed programme exit).
