JVM Fatal Error While Running Java FFI Tests For v1.39

[feidens]

While running make test_mcl in /ffi/java to compile the Java bindings for version v1.39, the tests crash via a fatal error of the JVM. Maybe related to #104.

The error results in the following log file: hs_err_pid26515.log

System: MacBook Pro (late 2012) i7 "Ivy Bridge" (I7-3615QM)

Thank you for the report and I'm sorry that I reproduce the bug. I've fixed the bug at https://github.com/herumi/mcl/issues/113 and v1.40. I've append the test without adox/adcx at GitHub Action and so I don't expect that the bug will happen again.

Apparently the above error is not fixed. hs_err_pid44286.log

I did not read the attached log because of Maybe related to #104..

Does the following command run well?

make clean
make lib/libmcl.a bin/pairing.exe bin/emu -j4

bin/pairing.exe
bin/emu

I tested them with https://software.intel.com/content/www/us/en/develop/articles/pre-release-license-agreement-for-intel-software-development-emulator-accept-end-user-license-agreement-and-download.html , then -ivb(Ivy Bridge CPU) shows an error and -hsw(Haswell CPU) does not.

% sudo sde -ivb bin/emu
TID 0 SDE-ERROR: Executed instruction not valid for specified chip (IVYBRIDGE): 0x7fff20612a89: vpbroadcastb ymm0, xmm0

Can be closed since everything works now. A new checkout solved it, hence it was my fault by not cleaning temp files or so. Sorry for the extra work.

Okay, the sde shows an error for int main() { puts("hello"); }, so we can use it for emulating Ivy Bridge.
