Bug ID: 57775
Summary: default argument for template parameter error for
friend definition in template
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED

MinGW4.7.2 cannot not parse a very simple code like following,
source code:
template <class T=void> struct X
{
friend void f(){
struct Y{}; // line 6
}
};
command and result:
C:\Users\HJ>g++ -v -Wall -Wextra -c tmp.cpp

The problem still exists for gcc 4.9.0 20130616 (experimental). It sounds a bit
familiar to me, though.

Bug ID: 57798
Summary: Incorrect handling of sum over first dimension of a
product of automatic arrays
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: stephan.kramer at imperial dot ac.uk
The test code below results in a segfault evaluating the sum() in the print
statement. This is compiling with gfortran 4.8.1 (4.8.1-4ubuntu1 on Ubuntu
Saucy) without any flags. If bounds checking is switched on (-fbounds-check) I
get a bounds violation error with a random number reported for one of the
bounds:
Fortran runtime error: Dimension 1 of array 'func' has extent 2 instead of
4196256
Is this possibly related to the optimisation requested in
http://gcc.gnu.org/bugzilla/show_bug.cgi?id6841 ?
program test
implicit none
call sub(2, 11)
contains
function func(m, n)
integer, intent(in):: m,n
real, dimension(m, n):: func
func = 0.0
end function func
subroutine sub(m, n)
integer, intent(in):: m, n
real, dimension(m,n):: y
y = 0.0
print *, sum(y*func(m,n), dim=1)
end subroutine sub
end program test
