I can't reproduce this. It builds fine for me with this command. (Is there something unusual about your system, e.g. low memory?)

Mech0n commented 1 year ago

I have enough memory. and this is my gcc version, i installed two gcc:

gcc (Ubuntu 7.5.0-6ubuntu2) 7.5.0
gcc-8 (Ubuntu 8.4.0-3ubuntu2) 8.4.0

➜  ~ gcov --version
gcov (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0

Probably a GCC bug, see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66209 and https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64928

Mech0n commented 1 year ago
