Package: libpari-dev Version: 2.13.0-2 Severity: grave The last pari upload broke giac on amd64, arm64 and mipsel :
https://buildd.debian.org/status/fetch.php?pkg=giac&arch=amd64&ver=1.6.0.25%2Bdfsg1-2%2Bb1&stamp=1604135053&raw=0 The failing test on amd64 is a segfault. I could check that running the failing test by hand while exporting PARI_SIZE=1024000 makes the problem disappear, and PARI_SIZE=512000 or nothing makes it come back ; here is an abstract from giac's pari.cc: static struct pari_constants_initialization { pari_constants_initialization () { if (getenv("PARI_SIZE")){ string pari_size_s(getenv("PARI_SIZE")); pari_mem_size= atoi(pari_size_s.c_str()); } entree * ptr=functions_basic; for (;ptr->name;++ptr){ pari_function_table[ptr->name]=ptr; } } } pari_constants_initialization_singleton; static void call_pari_init() { // do not initialize INIT_JMP so that PARI error do not exit pari_init_opts(pari_mem_size,pari_maxprime,INIT_SIGm | INIT_DFTm); paristack_setsize(pari_mem_size, (1<<30)); // initialize variable ordering x,y,z gp_read_str("[x,y,z,t]"); } Since it worked with pari 2.11 and breaks with pari 2.13, I guess the problem is on pari's side. Setting severity to grave because it breaks another package. I hope it helps, JP
