| Steps To Reproduce | Attempt to compile, without libsodium having been manually installed. | ||||
| Additional Information | I have two unrealircd servers. Upgrade succeeded on Debian x64 system.

In our buildbot we test compile with aarch64 on a raspberry pi 5 VM with 2GB memory. But libsodium package is installed there. I noticed you said it also crashed if you did have libsodium system package but then it crashes later (quoting you):gcc -I/usr/src/unrealircd-6.2.3/include -I/usr/src/unrealircd-6.2.3/extras/argon2/include -g -O2 -fno-strict-aliasing -fno-common -funsigned-char -Wall -Wextra -Waggregate-return -Wformat-nonliteral -Wduplicated-cond -Wduplicated-branches -Wparentheses -Wno-pointer-sign -Wno-format-zero-length -Wno-format-truncation -Wno-format-overflow -Wno-unused -Wno-unused-parameter -Wno-unused-but-set-parameter -Wno-char-subscripts -Wno-sign-compare -Wno-empty-body -Wno-deprecated-non-prototype -Wno-unterminated-string-initialization -Wno-pragmas -std=gnu17 -fno-strict-overflow -D_FORTIFY_SOURCE=3 -fstack-protector-all -Wstack-protector --param ssp-buffer-size=1 -fstack-clash-protection -mbranch-protection=standard -fstrict-flex-arrays=3 -ftrivial-auto-var-init=zero -fPIE -c unrealdb.c

Please submit a full bug report, with preprocessed source (by using -freport-bCould it be that it is out of memory? Even though you are also on 2GB hmm.. For the make step during configure, so during compiling of libraries we do have a bit weird algorithm at the moment: if [ "$LOWMEM" = 0 ]; then
echo "Running with 4 concurrent build processes by default (make -j4)."
export MAKE='make -j4'
else
echo "System detected with less than 750MB available memory, not forcing parallel build."
fiSo it is 1 process or 4, nothing in-between :D. We should probably tweak that to like 2 processes or something for xxxx memory. |

I think you hit a memory limit here but it could also be some compiler bug. To work around it you could, after running ./Config, edit the Makefile, and there remove the -O2 part from XCFLAGS. The compiler should take a lot less memory without -O2. If that still doesn't work then try -O0 (minus O zero). Hope that helps :) |

Managed to remove libsodium system lib on my system (sortof), then I get this error... so not a compiler crash with SIGBUS or SIGSEGV that you had, but a fatal error:crypto_ipcrypt/ipcrypt_armcrypto.c:356:65: error: incompatible type for argument 2 of 'vorrq_u8'

Oh and the bugs alice and i get are known and fixed in libsodium: https://github.com/jedisct1/libsodium/issues/1502 https://github.com/jedisct1/libsodium/issues/1509 ...specifically on aarch64 On January 11 2026 someone asked if they could release a 1.0.22, but they didn't do that yet. |

RAM does not seem to be the problem. 2 GB physical RAM, 1.5 GB swap. Swap is not touched. I watched a compilation with 'watch free' running and it doesn't appear that RAM usage got much over 300 MB. Swap was never used. System settled down to 166 MB used after compilation failed. Overriding the makefile to remove '-O2' (again, with libsodium manually installed) makes compilation succeed. So there are two problems here for sure. |

Yeah indeed. On IRC i concluded it is probably due to that new(er) gcc version. And there were other reports of that gcc version crashing. It will probably be fine on next gcc dot release or something. But the other issue, the regular compiler error, that you triggered by talking about this, is a real thing... it doesn't compile at all for me or alice. And this is a known issue on their github and fixed. So I'll have to replace the .tar.gz. Will keep this issue open for that. |

I've also updated my BuildBot so it compiles with shipped libraries (so --without-system.....everything... basically). This runs on any changes in extras/. This works correctly if triggered manually: it fails on the pi5 arm64 with gcc and succeeds with clang. Also all other archs/builders it succeeded. Anyway, that should help us with catching these issues in the future when we update dependencies and/or if some standard compiler hates one of our shipped libs. |
