--- Comment #21 from Surya Kumari Jangala <jskumari at gcc dot gnu.org> ---
There are two options to resolve the issue:
1. Use the BIND(C) directive on the fortran callee (DGEBAL) to make it
interoperable with the caller which is written in C. As described in comment
19, using this directive removed accesses to the caller's frame.
2. As described in
(https://gcc.gnu.org/onlinedocs/gfortran/Argument-passing-conventions.html),
since the first parameter to DGEBAL is of type CHARACTER, there is an extra
hidden argument. Change the call to DGEBAL from dgebal (the flexiBLAS wrapper
routine) to take an extra argument. This causes the compiler to allocate a
parameter save area in dgebal's frame, as there are now 9 parameters but only 8
parameter registers.
