Test failure on x86_64 (file_test failed)

[KevLing]

Prerequisites

• [x] Checked the developer manual
• [x] Checked that your issue isn't already filed: https://github.com/issues?utf8=✓&q=repo%3Alibtom%2Flibtomcrypt
• [x] Checked that your issue isn't related to TomsFastMath's limitation that PK operations can by default only be done with max. 2048bit keys

Description

This issue is the same as #258 but on a different platform. Running the libtomcrypt unit tests produces a failure (file_test) and a nop (katja_test). I am building this using GCC (6.4.0) on Windows 7 64-bit.

FAILURE: passed=19 failed=1 nop=1 duration=24.7sec real=24.7sec

Steps to Reproduce

1. Build tomsfastmath make CFLAGS="-DTFM_X86_64 -Isrc/headers" test

2. Build libtomcrypt with tomsfastmath make CFLAGS="-DUSE_TFM -DTFM_DESC -I../tomsfastmath/src/headers" EXTRALIBS="../tomsfastmath/libtfm.a" test

3. Run `test.exe.

4. I also tested with libtommath and saw the same test failure. Build command for libtommath was make. Then libtomcrypt was built with make CFLAGS="-DUSE_LTM -DLTM_DESC -I../libtommath" EXTRALIBS="../libtommath/libtommath.a" test

Version

libtomcrypt = v1.18.1 tomsfastmath = v0.13.1 libtommath = v1.0.1

Cygwin, GCC (6.4.0), Windows 7 64-bit

Additional Information

The test program's output with tomsfastmath and LTC_DEBUG=2 is attached.

Could you please run from cygwin's command prompt the following:

$ sha256sum tests/test.key
76ec7faebdc42a4de35ca70024c2d273e9f7856ca61612e89f5f66350ba8cf5f *tests/test.key

The tests/test.key is a text file and there might be some git related issue with CR+LF / LF newline autoconversion.

[sjaeckel]

very good catch!

$ unix2dos tests/test.key 
unix2dos: converting file tests/test.key to DOS format ...
$ sha256sum tests/test.key 
d3052a1401ae74febbfd96084346f2f4877a7cdd8e8ca0d2197d8fcfeaf3378d  tests/test.key

[sjaeckel]

a nop (katja_test)

and that nop is intentional as katja is disabled by default (and I guess could even be removed in the next release)

[karel-m]

katja [...] removed in the next release
