Since this causes no issues with GCC, I might enable it permanently in ~/.eclrc then. Would it be very hard to only disable this where compilers are known to have problems? Which compiler was it, and did its build also rely on autoconf etc? Other than allowing to see the transient .data file, another possible advantage would be the static constant data being loaded in read-only, non-executable pages (i.e. placed in the rodata section). But I didn't check yet how ECL loads its data, and it potentially also could use mmap+mprotect+madvise etc where wanted...
