This might be the reason of the problem you > are observing. I'll follow-up on this. I've tested now the current branch c6c7b30e4b compiling 32bit --with-wide-int. I have the impression that all 32bit --with-wide-int specific issues have been solved here or in the other related threads. All the compiler testsuite is running clean for me and I think we should classify the segfault Eli observed running `comp-tests-bootstrap' as a libgccjit bug specific to that version (libgccjit should *never* crash and if does it's a bug in the library). Eli, how do you find the current branch stability on 32bit wide-int? Is there anything left we should look into for this bug? Thanks Andrea
