I was trying to compile a new version of 3.7.3, and I noticed the following.
First, when building the library, I see, at the end:
CLINKER /opt/petsc-3.7.3/arch-darwin-c-debug/lib/libpetsc.3.7.3.dylib
ld: warning: could not create compact unwind for _dhseqr_: stack subq
instruction is too different from dwarf stack size
DSYMUTIL /opt/petsc-3.7.3/arch-darwin-c-debug/lib/libpetsc.3.7.3.dylib
Next, when I try to run the tests, I see:
Running test examples to verify correct installation
Using PETSC_DIR=/opt/petsc-3.7.3 and PETSC_ARCH=arch-darwin-c-debug
