--- Comment #20 from Martin Liška <marxin.liska at gmail dot com> --- Looks like the compilation goes further, but another gcc_assert is reached: 0x51f015 add_symbol_to_partition_1 ../../gcc/lto/lto-partition.c:187 0x51f5ba lto_balanced_map() ../../gcc/lto/lto-partition.c:534 0x516c0e do_whole_program_analysis ../../gcc/lto/lto.c:3201 0x516c0e lto_main() ../../gcc/lto/lto.c:3341 https://github.com/marxin/gcc/blob/master/gcc/lto/lto-partition.c#L185-L186 We can either wait for your complex patch or try to debug it.
