[Bug 1848795] [NEW] Internal error in varasm.c

[Steve Wartik]

Public bug reported:

I am running g++ 7.4.0 on Ubuntu 18.04 (18.04.3 LTS). The full version
line from g++ is:

    g++ (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0

The error message is:

    /home/ilab-user/ida-fabric-core/test/integration-tests/it-02
/expected-results.cpp:497:1: internal compiler error: in
output_constructor_regular_field, at varasm.c:5030

The command line that generates the error is:

/usr/bin/c++  -DSTANDALONE -I/home/ilab-user/ida-fabric-core/test
/integration-tests/it-02/../../../include -I/home/ilab-user/ida-fabric-
core/test/integration-tests/it-02/../../../src/common  -g -fPIE   -Wall
-g -std=gnu++11 -o CMakeFiles/it-02.dir/expected-results.cpp.o -c /home
/ilab-user/ida-fabric-core/test/integration-tests/it-02/expected-
results.cpp

I have attached the preprocessed output.

The output of apt-cache policy g++ is:
