Bug #: 52825
Summary: incorrect message for "incompatible pointer type" with
typedeffed structs
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: c
AssignedTo: [email protected]
ReportedBy: [email protected]
presented with the following code:
typedef struct
{
/*doesn't matter what's here*/
}
foo;
void f(foo*);
void main(int argc, char** argv)
{
struct foo* bar;
f(bar);
}
compiled with "gcc -c test.c", the following warning is produced:
test.c: In function 'main':
test.c:12:2: warning: passing argument 1 of 'f' from incompatible pointer type
[enabled by default]
test.c:7:6: note: expected 'struct foo *' but argument is of type 'struct foo
*'
The two types printed are the same, but the actual types are more like "foo*"
vs "struct foo*" (which are what clang mentions in its warning here).
