Public bug reported:
Hello,
I'm developing yet another c++ wrapper for BLAS libraries.
I've received an internal error (segmentation fault) from g++
7.3.0-27ubuntu1~18.04 and the same error from 8.2.0-1ubuntu2~18.04.
The exact error text is:
.......
g++-8 -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"test.d" -MT"test.o" -o
"test.o" "../test.cpp"
../test.cpp: In function ‘void test_shape_creator()’:
../test.cpp:19:18: internal compiler error: Ошибка сегментирования
blaspp<1> v({14});
^
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-8/README.Bugs> for instructions.
.......
Unfortunately, my code is enough complicated and probably does not have
proper logic currently.
I tried to simplify the code. But I failed to do it in a reasonable time. So I
changed my code to bypass the issue.
There are 2 big headers about 1000 rows each and two small cpp-files.
I've read that you do not want such files.
So, please inform me if you agree to work with my sources.
gcc info:
Using built-in specs.
