--- Comment #7 from Tobias Burnus <burnus at gcc dot gnu.org> --- I was wondering whether setting GCN_STACK_SIZE= would help; default is 32*1024. Answer: it does not seem to help, but I noticed that from time to time, it succeeds. I have a couple in a semi-row, but then 20 more with an endless loop or deadlock; thus, no idea how often it will work by chance - but it seems to be rather seldom.
