Public bug reported:
Having the below struct-structure, the compiler fails with internal
error:
struct xxxx_option
{
const char *option;
const char *description;
};
struct xxxx_menu_sub
{
const char *category;
struct xxxx_option option [];
};
struct xxxx_menu_sub menu [] =
{
{
"MENU1",
{
{ "a", "AAA" },
{ "b", "BBB" }
}
},
{
"MENU2",
{
{ "c", "CCC" },
{ "d", "DDD" }
}
}
};
# cc src/structerror.cpp -o build/structerror
src/structerror.cpp:45:1: internal compiler error: in
output_constructor_regular_field, at varasm.c:5030
}
^
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-7/README.Bugs> for instructions.
Removing "MENU2", "c" and "d": The compilation works.
# gcc -v
