[OE-core] gcc - internal compiler error: Segmentation failt

[Peter Bergin]

Hi,

I'm working with thud branch and have run into a bug in gcc. I would 
like help how to proceed with this.

Compiling the following C code gives Segmentation fault in gcc:

#include <stdio.h>
#include <string.h>
#include <stdint.h>

int main(void)
{
     const int32_t BUFFER_MAX_LENGTH = 4096*1024;
     char buffer[BUFFER_MAX_LENGTH];

     if (strncmp(&buffer[8], "ABC", 3) == 0)
         return 1;

     return 0;
}


Error:

| during RTL pass: expand
| /work/yocto/metrum-r3/build/tmp/work/armv7at2hf-neon-poky-linux-gnueabi/compiler-test/1.0-r0/work/git/tmp/strncmp.c: In function 'main':

|   if (strncmp(&buffer[8], "ABC", 3) == 0)
|       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I would like this fixed in thud branch and took a quick look in gcc repo 
for solutions. I had no luck finding anything useful. Anyone seeing this 
before? Anyone having suggestion how to proceed? Shall I create a 
bugzilla in Yocto?

Thanks,
/Peter
