warning: no debug symbols in executable (-arch x86_64)

Same when starting a debugger:

warning: (x86_64) /usr/local/opt/slepc/real/lib/libslepc.3.6.dylib empty dSYM file detected, dSYM was created with an executable with no debug info.

C/Fortran flags seems to have debug flags:

Using C/C++ linker: /usr/local/bin/mpicc

Using C/C++ flags: -Wl,-multiply_defined,suppress -Wl,-multiply_defined -Wl,suppress -Wl,-commons,use_dylibs -Wl,-search_paths_first -fPIC -Wall -Wwrite-strings -Wno-strict-aliasing -Wno-unknown-pragmas -g3 -O0

Using Fortran linker: /usr/local/bin/mpif90

Using Fortran flags: -Wl,-multiply_defined,suppress -Wl,-multiply_defined -Wl,suppress -Wl,-commons,use_dylibs -Wl,-search_paths_first -fPIC -Wall -Wno-unused-variable -ffree-line-length-0 -Wno-unused-dummy-argument -g -O0

Any ideas?

Kind regards,

Denis

I am answering the SLEPc-related questions:
- Having different number of iterations when changing the number of processes is normal.
- Yes, if you do not destroy the EPS solver, then the preconditioner would be reused.

Regarding the segmentation fault, I have no clue. Not sure if this is related to GAMG or not. Maybe running under valgrind could provide more information.
