Error if compillef using -O2

[AlexKurek]

Dear Authors,

Im getting the following error if optimization flags -DCMAKE_CXX_FLAGS="-O2 -march=native -DNDEBUG" were used:

DEBUG node.lof7.executable_args.Ateam_LBA_CC.skymodel: /opt/lofar/bin/makesourcedb stdout: /opt/lofar/bin/makesourcedb: Version GvD 2013-May-16
WARNING node.lof7.executable_args.Ateam_LBA_CC.skymodel: /opt/lofar/bin/makesourcedb stderr: Caught exception: BlobIStream: getStart should be done first
ERROR node.lof7.executable_args: Command '/opt/lofar/bin/makesourcedb' returned non-zero exit status 1

Full LOFAR soft and BEAM are also compilled using such flags, but this is so far not causing any error.

Full log attached.

Thanks for reporting, @AlexKurek . This is a know issue, described in #109. The cause is -DNDEBUG. I don't know why exactly, someone would have to analyze the problem more carefully. When I discovered optimizations weren't turned on, I did add -O3 and -march=native manually in #107 ( 31fc93e ), so most of the optimizations are always turned on. I'll close this bug, if you want to comment further please use #109 .
