Summary: [OOP] Segfault when running
gfortran.dg/class_allocate_6.f03
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Keywords: wrong-code
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: bur...@gcc.gnu.org
CC: ja...@gcc.gnu.org
This might be a known problem, but the test case
gfortran.dg/class_allocate_6.f03
fails for me. (The test was added for PR 45451 / PR 46174, which does a deep
copy.)
To be precise, I get a segfault using when executing the line:
allocate(y, source=x)
A "PRINT" statement placed directly after that line will not be printed, i.e.
it is not a finally/cleanup issue.
The segfault disappears if I unset MALLOC_PERTURB_ which indicates the use of
an uninitialized variable.
Valgrind shows:
Conditional jump or move depends on uninitialised value(s)
