Hi,
can you please test add this following snippet of code to end of
function msadams_failurehandler(), just before "return GSL_SUCCESS;" and
try behavior again, thanks! You should see that line printed in output.
Does it still crash? PS. I created bug report, this is [bug #52230].
if ((int)state->ordprev - (int)ord >= 2)
{
printf("TKDEBUG: MSADAMS ORDER CHANGE: ord %d ordprev %d\n",
(int)ord, (int)state->ordprev);
msadams_reset (vstate, dim);
}

Thanks! Looks like the solver hits a bump while accelerating on a high
gear. That should not be a problem, though. I'll take a look at the
code, but it will take time.
Meanwhile, if you have time, you can add "#define DEBUG" in the
beginning of msadams.c and recompile GSL. This should make msadams
print out _lots_ of debug info and data, that would help decipher this
issue. Interesting stuff happens between t=5116.13 and t=5116.27.
Yeah, wasn't quite expecting a 1 GB output file. Attached is a truncated
section that has the steps in question. I've prefixed "PROGRAM" to the
output lines that are not coming out of msadams.c
