Bug ID: 89832
Summary: confusing error message when there is a problem with
ASAN_OPTIONS "ERROR: expected '='"
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: sanitizer
Assignee: unassigned at gcc dot gnu.org
Reporter: diane2332 at gmail dot com

Target Milestone: ---
When using AddressSanitizer on a very large software system involving multiple
binaries, libraries, etc., it is very difficult to know where an error message
is coming from when all I get is:
ERROR: expected '='
I eventually traced this to libasan.so.
It would have been so much easier if perhaps the message was:
AddressSanitizer: ERROR: expected '=' in ASAN_OPTIONS
Example follows.
hello.c:
#include <stdio.h>
int main()
{
printf("Hello world\n");
return 0;
}
gcc --version
