Build Identifier: HEAD Create a source file with the following content (possibly it requires the GNU Linux headers): #include <sys/stat.h> int main() { struct stat entryInfo; lstat("a", &entryInfo); // ERROR return 0; } The indexer reports the call to lstat as ambiguity. Reproducible: Always
Can you share the declarations for 'lstat' that are considered? You should be able to find them using 'F3' on 'lstat'.

Don't know whether that helps, this is the raw text from the header files, you possibly also need the macros: extern int lstat (__const char *__restrict __file, struct stat *__restrict __buf) __THROW __nonnull ((1, 2)); extern __inline__ int __NTH (lstat (__const char *__path, struct stat *__statbuf)) { return __lxstat (_STAT_VER, __path, __statbuf); }

When I add __restrict to the definition, or remove it from the declaration, everything is fine.
Here is a smaller example: void someFunction(int * __restrict a); void someFunction(int * a) { } int main() { int number = 5; someFunction(&number); return 0; } Don't know whether this code is valid, but expanding lstat.h one my system resulted in this.
Thanks, I can see two issues: * Whereever cv-qualifiers are removed the restrict-qualifier needs to be removed also. (Affects function-types and template-instantiation) * The restrict-qualifier needs to be considered during overload resolution. An example for overloading would be: void f(int * __restrict* a) {} void f(int ** a) {} // different function void test() { int* restrict rnumber= 0; int* number = 0; f(& f(&number); // calls f(int** a) return 0; }
