Here's something i got from running dbx with benchmark (with "check -access" option
to detect illegal memory access):

Algorithm generate 100*sign 100*verify

RSA 1024 bit Read from uninitialized (rui):
Attempting to read 1 byte at address 0xffbfeba8

which is 312 bytes above the current stack pointer

stopped in add_randomness at line 1085 in file "random-csprng.c"
1085 rndpool[pool_writepos++] ^= *p++;
(dbx)

Hope this helps solve the issue.

I'm sorry, do you mean the zip file that i uploaded earlier? That was just
screenshots of the output message which i listed in my second post. It's just
benchmark and keygen, and i am pretty sure both errors are related to ECC key
generation.

It's my first time using this site, please let me know if i need to provide more
information. And thanks!

Can't seem to edit my first post, so create this second post to provide extra info.

Ran all tests in libgcrypt/libgcrypt-1.6.4/tests directory, benchmark and keygen
failed. Here's the output:

./benchmark --verbose
