From: bangerth@dealii.org To: dagraz@radiance.com, gcc-bugs@gcc.gnu.org, gcc-prs@gcc.gnu.org, nobody@gcc.gnu.org, rutt@chezrutt.com Subject: Re: c++/8493: Bad interaction of strlen builtin and overload resolution Date: Thu, 07 Nov 2002 15:15:00 -0000 [thread overview] Message-ID: <20021107231515.10422.qmail@sources.redhat.com> (raw) Old Synopsis: Outputing strlen() to ostream causes bogus compiler error New Synopsis: Bad interaction of strlen builtin and overload resolution State-Changed-From-To: open->analyzed State-Changed-By: bangerth State-Changed-When: Thu Nov 7 15:15:14 2002 State-Changed-Why: Confirmed. This can be reduced to the following: ---------------------------------- typedef unsigned int size_t; extern size_t strlen (__const char *__s) throw () __attribute__((__pure__)); static void foo(size_t); static void foo(double); main() { foo(strlen("hello")); } ---------------------------------- Which gives me with 3.2.1 and 3.3: tmp/g> /home/bangerth/bin/gcc-3.3x-pre/bin/c++ -c y.ii y.ii: In function `int main()': y.ii:8: error: call of overloaded `foo(<anonymous>)' is ambiguous y.ii:4: error: candidates are: void foo(unsigned int) y.ii:5: error: void foo(double) This used to work with 2.95, but does no more; I think the time for marking regressions with "high" has passed, so I leave it in the present "medium" state. http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=8493
