Dear mips porters, I am maintaining the gnuplot in the Debian and there is a segfault on the mipsel, what I reported to upstream [1].
There is a question from the gnuplot author, which I am not able to response. Could you please have a look? It segfaults somewhere in the static global structure. And the problem appeared recently, maybe due to the GCC-9 migration. There were not problems with GCC-8. Some regressions? [1] https://sourceforge.net/p/gnuplot/bugs/2195/ Thank you Anton Am Di., 3.
