Bug #: 50368
Summary: Implicit, precision losing cast in objc/objc-api.h
Classification: Unclassified
Product: gcc
Version: 4.6.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libobjc
AssignedTo: [email protected]
ReportedBy: [email protected]
Hy,
I'm using (or trying to) libojc in conjunction with clang.
In this particular case it's compiling with -Wall -Werror, and stumbles over an
implicit cast in objc/objc-api.h:
/usr/lib/gcc/x86_64-unknown-linux-gnu/4.6.1/include/objc/objc-api.h:291:38:
error: implicit conversion loses integer precision: 'long' to 'int'
[-Werror,-Wshorten-64-to-32]
return CLS_ISCLASS(_class)?_class->version:-1;
Even without -Werror this would still generate a annoying and potenitally
confusing warning. It would be great if this cast could be made explicit in
future versions.
Regards,
Florian
