| Summary | 0006591: OOM kill because of low memory during installation | ||||
| Description | Upgrade fails at this stage: CC src/libpcre2_8_la-pcre2_match.lo gcc: internal compiler error: Killed (program cc1) Please submit a full bug report, with preprocessed source if appropriate. See <file:///usr/share/doc/gcc-6/README.Bugs> for instructions.

| Steps To Reproduce | Run ./Config or ./unrealircd upgrade on low memory machine. | ||||
| Additional Information | Temporary solution is to use less aggressive C optimization : CFLAGS="-O1" ./Config This flag didn't work for me with ./unrealircd upgrade.
