Summary: "internal compiler error" when using type-bounded
function returning vector
Product: gcc
Version: 4.5.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: wangmianz...@linuxmail.org
Created attachment 24903
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=24903
a reduced example
when compiling "reducedcase.f90", a code using type-bounded function returning
vector:
$ gfortran -o reducedcase reducedcase.f90
reducedcase.f90: In function ‘test’:
reducedcase.f90:18:0: internal compiler error: in gfc_conv_variable, at
fortran/trans-expr.c:551
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.5/README.Bugs> for instructions.
I think this code should be valid according to fortran 2003 standard.
Even if it is not valid, I think better error handling would be good.
many thanks.
