exception with purify in bn_mont.c:402 (v=bn_mul_add_words(rp,np,nl,(rp[0]*n0)&BN_MASK2);)

[Rohit Omar]

Hi

 

I am getting exception in crypto\bn\bn_mont.c:402
(v=bn_mul_add_words(rp,np,nl,(rp[0]*n0)&BN_MASK2);) while executing with
Rational purify. I think bn_mul_add_words called as assembly code from
crypto\bn\asm\bn_win32.asm.

 

Please see following stacktrace
