And I just duplicated with 32-bit code on Solaris. I have not been able to test ARM A-32. GMP build is broken.

(I'm guessing cd somewhere and and valgrind ). Jeff ___ nettle-bugs mailing list nettle-bugs@lists.lysator.liu.se http://lists.lysator.liu.se/mailman/listinfo/nettle-bugs

Try running the test program under valgrind > and/or asan? Thanks Niels. I'll try to get to it later tonight or tomorrow. In the meantime you might provide your test data to GMP. It looks like it would make a good test case for them. Jeff ___ nettle-bugs mailing list nettle-bugs@lists.lysator.liu.se http://lists.lysator.liu.se/mailman/listinfo/nettle-bugs

To debug, it would be helpful to know 1. The value of enb and windowsize at the crash. 2. The definition of POWM_SEC_TABLE (defined in the platform specific gmp-mparam.h), and used by the win_size function in this file. To me, it looks like the assert validates that POWM_SEC_TABLE confoems to expectations. It might also be a bug in the book-keeping of scratch space, leading to some memory overwrite.
