Bug ID: 69185
Summary: bounds-check gives false positive on assignment to
allocatable array
Product: gcc
Version: 4.9.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: townsend at astro dot wisc.edu
Target Milestone: ---
Created attachment 37255
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=37255&action=edit
Source code of program reproducing the problem
Compile the attached code with:
gfortran -fbounds-check -std=f2003 -o foo foo.f90
On execution, the assignment to b should be OK, since b will be allocated to
match the shape of the RHS (as per F2003). However, the following run-time
error instead occurs:
At line 8 of file foo.f90
Fortran runtime error: Array bound mismatch for dimension 1 of array 'b' (20/4)
The problem does not arise if I use, e.g., 'a' on the RHS instead of 'exp(a)'.
