Bug #: 55174
Summary: internal compiler error: Segmentation fault with bad
array reference
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: john.har...@vuw.ac.nz
This 4-line Fortran program has an error at line 3, where array(*) is of course
not permitted as an argument of a function.
implicit none
integer:: array(2)=(/42,666/)
print *, size(array(*))
end
Other compilers (g95, ifort) correctly diagnose the error but gfortran 4.8.0
gives an internal compiler error: Segmentation fault and asks me to tell you.
My compile-time output follows.
