[CWB] Segmentation fault

[Hardie, Andrew]

Trying to create a 3.0.3 binary release has revealed what may be the problem. 

With the configuration "site=standard", the build is fine. With the configuration "site=linux-release", the linker fails with the following messages:

The only setting that's different seems to be 

SITE_LDFLAGS = -static

... in the case which failed. So, I have turned that off  that to create a 3.0.3 release, which I will post to the site presently.

(This makes me suspect that something in static vs dynamic linking having changed may be the reason the old binaries segfault in buster. Though if so it would be weird that it does not also affect Ubuntu etc.)

Right - so it might just be wrong version; I will adapt the script and test it again next time I install Debian for my test; but it might be a good plan in that case to update the SourceForge page, since I just copied the links from what I thought was the recommended source:
