kcc can't compile wrk

[Lycbel]

#kcc can't compile the C project wrk, for the first error: #"out of memory" I created the minimized input to reproduce it. You can run the following command

if [ -f "run.sh" ];then
rm run.sh
fi
wget https://raw.githubusercontent.com/Lycbel/cs510Files/master/report4/report_wrk/minimized_input/run.sh
bash run.sh

kcc ran out of memory when trying to build wrk on your computer? What was the exact message? Have you tried maybe increasing the stack size limit (ulimit -s)?

[Lycbel]

as it is LuaJIT problem, it is moved to LuaJIT's problem

update on wrk: the previous problem is caused by LuaJIT, but I can work around by using the lib which is compiled by gcc. however there is still problems with src of wrk: units.c the compilation will fail with the error:

src/units.c:17:1: error: Encountered an unknown error. This may be due to encountering undefined behavior, an unsupported language feature, or a bug in this tool.

I created the minimized input and bash file to run it the minimized input unit.c:

#include <stdlib.h>
#include <stdio.h>
typedef struct {
    int scale;
    char *base;
    char *arr[];
} units;
units time_units_us = {// here will have the same problem
    .scale = 1000,
    .base  = "us",
    .arr = { "ms", "s", NULL } 
};

int main()
{
     printf("can work with gcc%d",time_units_us.scale);
     return 0;
}

output:

units.c:8:1: error: Encountered an unknown error. This may be due to encountering undefined behavior, an unsupported language feature, or a bug in this tool.

    Unknown error (UNK-1)

to run it:

wget https://github.com/Lycbel/cs510Files/blob/master/report6/wrk/wrk.zip?raw=true -O wrk.zip
unzip wrk.zip
cd wrk
bash run.sh
