From 615ae55eca17c1632e23f52c5842bb338d633ddf Mon Sep 17 00:00:00 2001 From: Fred Drake Date: Fri, 30 Jun 2000 16:20:13 +0000 Subject: Trent Mick : The common technique for printing out a pointer has been to cast to a long and use the "%lx" printf modifier. This is incorrect on Win64 where casting to a long truncates the pointer. The "%p" formatter should be used instead. The problem as stated by Tim: > Unfortunately, the C committee refused to define what %p conversion "looks > like" -- they explicitly allowed it to be implementation-defined. Older > versions of Microsoft C even stuck a colon in the middle of the address (in > the days of segment+offset addressing)! The result is that the hex value of a pointer will maybe/maybe not have a 0x prepended to it. Notes on the patch: There are two main classes of changes: - in the various repr() functions that print out pointers - debugging printf's in the various thread_*.h files (these are why the patch is large) Closes SourceForge patch #100505. --- Python/compile.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'Python/compile.c') diff --git a/Python/compile.c b/Python/compile.c index 4373422f31..c69a95f389 100644 --- a/Python/compile.c +++ b/Python/compile.c @@ -130,8 +130,8 @@ code_repr(co) filename = PyString_AsString(co->co_filename); if (co->co_name && PyString_Check(co->co_name)) name = PyString_AsString(co->co_name); - sprintf(buf, "", - name, (long)co, filename, lineno); + sprintf(buf, "", + name, co, filename, lineno); return PyString_FromString(buf); } -- cgit v1.2.1
