Hi

when  using AOCC-1.2.1 on a centos 7.5 machine, the compiler crashes with the following error message.

When compiling the same code with clang 6 pure, no error occurs at all

Thanks in Advance

Dirk

Hi dribbroc,

Would you be able to share the testcase, please?

[dribbroc]

Hi

I sent to you a repro case.

Additionally, the error is gone with AOCC 1.3.0

[dribbroc]

Another similar error arose with AOCC 1.3.0

But this time, its 'easy' to reproduce, as it happens while compiling a library called alglib.

http://www.alglib.net/translator/re/alglib-3.13.0.cpp.gpl.zip

in folder alglib/cpp/src you need to call

clang++ -I. linalg.cpp -c -std=c++11  -O3 -march=znver1

and get

summergames: src>$ clang++ -I. linalg.cpp -c -std=c++11  -O3
