compilation error

zzz403 — Wed, 28 May 2025 20:41:02 GMT

I got error when trying to compile .c file with icx-2024.2.0. Here is the command I use and the error message (I add -save-temps -v as it asked and upload those files):

$ icx ./icx.c -o./test -O3 -save-temps -v

PLEASE append the compiler options "-save-temps -v", rebuild the application to get the full command which is failing and submit a bug report to https://software.intel.com/en-us/support/priority-support which includes the failing command, input files for the command and the crash backtrace (if any).

Here is the kernel part I extract from my code:

#define N 16

#define M 10

for (int i = 0; i < N; i++) {

for (int j = 1; j < min(i,M+1); j++) {

A[j-1] = 2;

}

for (int k = 1; k < min(i,M+1); k++) {

A[k-1] = 3;

}

}

I found that the error disappears when I set "N" to 15. What's wrong with it?
