What is the commit id of the openssl version you're building?
The commit id is 1536bcfd567d6e369abac1fcaafd56bf7d16d7bb.
What is on line 179 of that file. I have:
s = tab[b & 0xF]; l = s;
and all slots from 0 to 15 of tab[] are initialized, while "b" is
a function argument.
Line 179 is identical to what you have, and "b" is a function argument.
In lines 174 to 177 all slots of tab[] are initialized:
tab[ 0] = 0; tab[ 1] = a1; tab[ 2] = a2; tab[ 3] =
a1^a2;
tab[ 4] = a4; tab[ 5] = a1^a4; tab[ 6] = a2^a4; tab[ 7] =
a1^a2^a4;
tab[ 8] = a8; tab[ 9] = a1^a8; tab[10] = a2^a8; tab[11] =
a1^a2^a8;
tab[12] = a4^a8; tab[13] = a1^a4^a8; tab[14] = a2^a4^a8; tab[15] =
a1^a2^a4^a8;
Maybe b is uninitialized?
