Re: [Patch, Fortran, OOP] PR 64230: [4.9/5 Regression] Invalid memory reference in a compiler-generated finalizer for allocatable component

[Paul Richard Thomas <paul.richard.thomas@gmail.com>]

Hi Janus,

The testcase has a dependence on libubsan.so, which my LD_LIBRARY_PATH
does not seem to be able to resolve. It therefore fails in the
regression test. When I point to ~/lib64, I get the message:

/svn/trunk/gcc/testsuite/gfortran.dg/class_allocate_18.f90:8: runtime
error: signed integer overflow: 214358001592 * 214358001560 cannot be
represented in type 'integer(kind=8)'

Cheers

Paul
