hi

I didn't use gcc 7.3.0 myself, I use gcc 8 and also older gcc 4.9.2. In 
both cases, I don't get any of the crash you get when using PMMU.

Maybe you could try to compile with debug mode (run ./configure 
--enable-debug) to see if it changes anything.
It should also reports some warnings during compilation for the cpu 
parts. All of them are supposed to be harmless, but could you attach a 
log file with the compilation results anyway, so I can compare with the 
warnings I get on my side to see if anything differ ?

Note, by default Hatari adds -O flag even in debug mode and maybe some 
optimisations are related to what you get with PMMU.

Could you also edit CMakeLists.txt on line 268 and comment this line :
set(CMAKE_C_FLAGS "-O ${CMAKE_C_FLAGS}")
then try again ./configure --enable-debug ; make clean ; make to see if 
the build works better in your case.

Sorry for all these tests, but it's hard to go further at the moment if 
I can't replicate any of your issues :(
