exceptions pulling an Abort Trap

[Riccardo Mottola]

Hi,

I have a strange issue on FreeBSD. I am running gnustep git head.

Ít is compiled with gcc7. I  am actually unsure which runtime is being used. I 
have libobjc2 installed as a package, I don't know if gnustep picks up that one 
or uses gcc's one.

I suppose though yes, this is the ldd of base:

now, applications are unstable, the get abort trap often and I think this is 
everytime an exception occours. This is the stacktrace of an examplle, but  it 
is always with raise/throg.

Program received signal SIGABRT, Aborted.

can it be that libobjc2 is incompatible with gcc if not compiled with it? or 
that base configure got confused?
Can I instruct gnustep to use gcc's runtime even if libobjc2 is present, as a 
"test" ?

I configured make with:
$ ./configure --prefix=/ --with-layout=gnustep CC=gcc7 CXX=g++7 CPP=cpp7

and base with no additional parameters.

configure says:
configure:5987: checking the Objective-C runtime
configure:5997: result: GNU
configure:6014: checking for custom shared objc library
configure:6073: result: NONE


but it will say GNU for both gcc's and David's runtime, right?

Actually, I fear that FreeBSD ships only libobj2 and that gcc7 is without objc 
runtime somehow.. it is strange, I find only one libobjc.so...

Thanks,
