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':

/work/yocto/metrum-r3/build/tmp/work/armv7at2hf-neon-poky-linux-gnueabi/compiler-test/1.0-r0/work/git/tmp/strncmp.c:16:6:
internal compiler error: Segmentation fault
| 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
