I think I fixed it but hitting an unexpected segfault before I can check, I can't even deduce where it might be coming from because it seems some local variables relied upon at the point of the segfault have somehow been 0'd out between the call to the add function (which is right above the line the segfault occurs on) and the usage of the local variable:
Code:ret = alu_reg_add( alu, NUM, VAL ); // between this call and the next line both NUM and VAL are somehow 0'd N = alu_reg_data( alu, NUM );I've tried debugging but I'm honestly lost on where to find the bug, if anyone has any ideas from looking at the project code I would appreciate you mentioning it even if it turns out to be a dead end.Code:make check.run cd ../ && make --no-print-directory check.run #MAKECMDGOALS=check.run cd mak && make -j 1 --no-print-directory -f main.mak check.run PRJ_GOALS=check PRJ_LIB_NAME=alu_d Checking 3rd Party libraries are upto date cd '../cloned/unic' && git fetch && git pull Finished checking PRJ_DST_BIN=check_alu_d.AppImage PRJ_DST_LIB=libalu_d.so cc -ggdb -D _DEBUG -O0 -fsanitize=address -fPIC -Wall -Wextra -pedantic -I ../cloned/unic/include -I ../include -D UNIC_FALLBACK -o ../src/alu_bit_d.o -c ../src/alu_bit.c cc -ggdb -D _DEBUG -O0 -fsanitize=address -fPIC -Wall -Wextra -pedantic -I ../cloned/unic/include -I ../include -D UNIC_FALLBACK -o ../src/alu_fpn_d.o -c ../src/alu_fpn.c cc -ggdb -D _DEBUG -O0 -fsanitize=address -fPIC -Wall -Wextra -pedantic -I ../cloned/unic/include -I ../include -D UNIC_FALLBACK -o ../src/alu_int_d.o -c ../src/alu_int.c cc -ggdb -D _DEBUG -O0 -fsanitize=address -fPIC -Wall -Wextra -pedantic -I ../cloned/unic/include -I ../include -D UNIC_FALLBACK -o ../src/alu_main_d.o -c ../src/alu_main.c cc -ggdb -D _DEBUG -O0 -fsanitize=address -fPIC -Wall -Wextra -pedantic -I ../cloned/unic/include -I ../include -D UNIC_FALLBACK -o ../src/alu_math_d.o -c ../src/alu_math.c cc -ggdb -D _DEBUG -O0 -fsanitize=address -fPIC -Wall -Wextra -pedantic -I ../cloned/unic/include -I ../include -D UNIC_FALLBACK -o ../src/alu_mem_d.o -c ../src/alu_mem.c cc -ggdb -D _DEBUG -O0 -fsanitize=address -fPIC -Wall -Wextra -pedantic -I ../cloned/unic/include -I ../include -D UNIC_FALLBACK -o ../src/alu_uint_d.o -c ../src/alu_uint.c cc -ggdb -D _DEBUG -O0 -fsanitize=address -fPIC -Wall -Wextra -pedantic -I ../cloned/unic/include -I ../include -D UNIC_FALLBACK -o ../src/alu_vec_d.o -c ../src/alu_vec.c cc -ggdb -D _DEBUG -O0 -fsanitize=address -fPIC -shared -o ../lib/libalu_d.so ../src/alu_bit_d.o ../src/alu_fpn_d.o ../src/alu_int_d.o ../src/alu_main_d.o ../src/alu_math_d.o ../src/alu_mem_d.o ../src/alu_uint_d.o ../src/alu_vec_d.o -Wl,-rpath,../lib cc -ggdb -D _DEBUG -O0 -fsanitize=address -fPIC -Wall -Wextra -pedantic -I ../cloned/unic/include -I ../include -D UNIC_FALLBACK -o ../tests/check_alu_d.o -c ../tests/check_alu.c cc -ggdb -D _DEBUG -O0 -fsanitize=address -fPIE -L ../lib -o ../bin/check_alu_d.AppImage ../tests/check_alu_d.o -Wl,-rpath,../lib -l alu_d -l check -l rt -l pthread -l m gdb -ex run ../bin/check_alu_d.AppImage GNU gdb (GDB) 9.2 Copyright (C) 2020 Free Software Foundation, Inc.
