So this is exactly the case which I suspected: It crashes when calling a DLL (shared object file) function. > What are the functions prefixed with "ht:"? This is a shared library in "lib/ht". It is compiled from "src/ht.c". PicoLisp has a special mechanism: When a function is undefined, but contains a colon, the interpreter tries to locate a shared lib given by the part before the colon (here 'ht'), and searches for a function with the remaining part (here 'Prin'). If it finds one, it defines the whole symbol (here 'ht:Prin') to that function. Then the code of 'Prin' is executed, after the library was loaded. Here something goes wrong on the Mac. The relevant code is in "src/main.c", in the function 'sharedLib()'. Basically, it does a 'dlopen()' on the library, and searches for the function with 'dlsym()'. In that course, heap memory seems to be destroyed. Cheers, - Alex -- UNSUBSCRIBE: mailto:picol...@software-lab.de?subject=unsubscribe
