This assumes that the problem Michael was referring to was with the library files, not dbd files.  If the problem is dbd files then of course static build won't help.

Another way to quickly check if Michael's hypothesis is correct is to change your IOC application CONFIG_SITE file to have STATIC_BUILD=YES.   That guarantees that the EPICS build-time and run-time libraries are identical.  If the problem goes away then you probably have a problem with conflicting .so files.  Check your LD_LIBRARY_PATH environment variable.

I've not seen this assertion fail in any other circumstance since I
added it.

The specific condition being detected is that the number of fields in
some recordtype is different between the runtime and buildtime definitions.

I suspect that, without intending to, you have epics modules in the
standard search paths (eg. /usr/local), or in your environment (eg. PATH
or LIBRARY_PATH), or perhaps some includes in configure/RELEASE.

I would suggest that you retry your builds in a completely clean
environment.  checkout/untar source into a fresh OS install (a VM would
be a quick way to do this).
