Package: gcc-4.9
Version: 4.9.2-16
Severity: normal
Dear Maintainer,
Trivial C program:
#include <stdio.h>
#include <pthread.h>
int main (void)
{ pthread_cond_t cond;
pthread_cond_init(&cond, NULL);
return 0;
}
Above works correctly when compiled and run (even under Valgrind) as:
gcc -Wall cond_init.c -o cond_init && valgrind ./cond_init
on both x86_64/linux and armhf/linux.
However, then compiled with -fsanitize=address as:
gcc -Wall -fsanitize=address cond_init.c -o cond_init && ./cond_init
it works correctly on x86_64/linux but gets a SIGSEGV on armhf/linux:
ASAN:SIGSEGV
=================================================================
==23193==ERROR: AddressSanitizer: SEGV on unknown address 0x00000000 (pc
0x00000000
sp 0xbeffefb0 bp 0x00000000 T0)
AddressSanitizer can not provide additional info.
SUMMARY: AddressSanitizer: SEGV ??:0 ??
==23193==ABORTING
Apparently this was a problem in gcc-4.8
https://code.google.com/p/address-sanitizer/issues/detail?id=297
but I'm using the Debian gcc-4.9 package.
