hi, thank you, at the point that the corruption exists, the line `.Internal(La_rs(x,FALSE))` actually breaks without needing `eigen`
i have provided a reproducible example but agree it might not be minimal -- i did try removing various sections, each time the bug unfortunately vanished. note the february 22nd edit: even interspersing the script with the line that triggers the crash prevents the crash in the first place! i think this occurs in C and not R, and would appreciate pointers about how one might do that? the only advice i've have is rebuilding R with a debug build and gdb, but this seems like a huge lift -- are there any shortcuts here for someone mostly unfamiliar with C code and even setup? general advice on this thread might also help me crack this case :) stackoverflow.com/questions/35455135/general-suggestions-on-debugging-internal-in-r thanks for your time On Tue, Feb 23, 2016 at 8:22 AM, Duncan Murdoch <murdoch.dun...@gmail.com> wrote: > On 23/02/2016 7:49 AM, Anthony Damico wrote: > >> hi, does anybody have a clue why .Internal(La_rs(x,FALSE)) is getting >> corrupted (actual detonation occurs within La_solve_cmplx within Lapack.c) >> on windows but not mac/unix? >> >> i have provided two (long) scripts that reproduce the problem and a third >> script modified to trigger the crash that unfortunately does not reproduce >> the problem >> >> >> http://stackoverflow.com/questions/35447971/internalla-rsx-false-crashes-r-after-long-reproducible-script-on-windows >> > > Just two comments: > > - Your post suggests you're calling .Internal() yourself, but that's not > the case.
