Dear all,

After upgrading to petsc 3.12.2 my solver program crashes consistently.
Before the upgrade I was using petsc 3.9.4 with no problems.

My application deals with a complex-valued, generalized eigenvalue problem.
The matrices involved are relatively large, typically 2 to 10 Gb in size,
which is no problem for petsc 3.9.4.
However, after the upgrade I can only obtain solutions when the matrices
are small, the solver crashes when the matrices' size exceed about 1.5 Gb:

[0]PETSC ERROR: Caught signal number 15 Terminate: Some process (or the
batch system) has told this process to end
[0]PETSC ERROR: Try option -start_in_debugger or -on_error_attach_debugger
[0]PETSC ERROR: or see
[0]PETSC ERROR: or try http://valgrind.org on GNU/linux and Apple Mac OS X
to find memory corruption errors
[0]PETSC ERROR: configure using --with-debugging=yes, recompile, link, and
[0]PETSC ERROR: to get more information on the crash.

and so on for each cpu.

I tried using valgrind and this is the typical output:

==2874== Conditional jump or move depends on uninitialised value(s)
==2874==    at 0x4018178: index (in /lib64/ld-2.22.so)

==2874==    by 0x40011F7: ??? (in /lib64/ld-2.22.so)
==2874==    by 0x12: ???

These are my configuration options. Identical for both petsc 3.9.4 and

./configure --with-scalar-type=complex --download-mumps --download-parmetis
--download-metis --download-scalapack=1 --download-fblaslapack=1
--with-debugging=0 --download-superlu_dist=1 --download-ptscotch=1
CXXOPTFLAGS='-O3 -march=native' FOPTFLAGS='-O3 -march=native'
COPTFLAGS='-O3 -march=native'

Thanks in advance for any comments or ideas!
