As a test, I set "-O2" in C*FLAGS to "-O0" in /etc/make.conf and recompiled
"sci-libs/clapack-3.2.1-r4".
=> the infinite loop seems to be eleminated and digikam's Refocus plugin (using
clapack) works flawless.

So I think the following line might fix this bug:
set_source_files_properties(dlamch.c slamch.c PROPERTIES COMPILE_FLAGS "-O0")
