Package: gcc-4.3 Version: 4.3.1-4 Severity: minor Compiling this with gcc-4.3 -Wall -c
int
main (void)
{
return "hello" == "there";
}
results in a warning:
hoh.c: In function ‘main’:
hoh.c:4: warning: comparison with string literal results in unspecified behavior
The warning claims the behaviour is unspecified.
But actually this comparison must always evaluate to false
because the strings consist of different characters and
must thus have different addresses.
For whatever reason, there are several comparisons like that
in net-snmp 5.2.3-7etch4.
A gcc-help thread about this warning indicates it is intended to
warn about only those uses that really are unspecified:
