Control: found 922323 0.9.20180101-1+b1 Control: tags 922323 + upstream
Dear Maintainer, I tried to have a look at this segfault, and guess I have found something. The problem seems to be, that the slirp library used by Basilisk is using some 32 bit types for pointers. Unfortunately this does not work in 64 bit systems. I could reproduce this also for current Buster/testing [2]. When I build a stretch package with ipqp_32 typedefed to a 64 bit type "void*" the crash does not happen [3]. (Just tested if the crash happens anymore, nothing further tested.) Basically it seems related to upstream issue [1]. So, I assume, the 32bit builds may work as expected. Kind regards, Bernahrd [1] https://github.com/cebix/macemu/issues/173 [2] (gdb) bt #0 0x000055f8148a580f in do_get_mem_word (a=0x100000000) at ./src/Unix/./sysdeps.h:428 #1 0x000055f8148a580f in get_word (addr=3200692224) at ./src/Unix/../uae_cpu/memory.h:143 #2 0x000055f8148a580f in m68k_disasm(unsigned int, unsigned int*, int) (addr=<optimized out>, nextpc=nextpc@entry=0x7f748bcbce74, cnt=0, cnt@entry=1) at ./src/Unix/../uae_cpu/newcpu.cpp:1440 #3 0x000055f8148a5e26 in m68k_dumpstate(unsigned int*) (nextpc=nextpc@entry=0x7f748bcbce74) at ./src/Unix/../uae_cpu/memory.h:171 #4 0x000055f8148a2427 in sigsegv_dump_state(sigsegv_info_t*) (sip=<optimized out>) at ./src/Unix/main_unix.cpp:287 #5 0x000055f814894a61 in handle_badaccess (sip=<optimized out>, scp=0x7f748bcbcf00) at ./src/Unix/../CrossPlatform/sigsegv.cpp:2651 #6 0x000055f814894a61 in sigsegv_handler(int, siginfo_t*, void*) (sig=<optimized out>, sip=<optimized out>, scp=0x7f748bcbcf00) at ./src/Unix/../CrossPlatform/sigsegv.cpp:2864 #7 0x00007f74909b7730 in <signal handler called> () at /lib/x86_64-linux-gnu/libpthread.so.0 #8 0x000055f8148ef4f5 in ip_slowtimo () at ./src/Unix/../slirp/ip_input.c:453 #9 0x000055f8148ee265 in slirp_select_poll (readfds=readfds@entry=0x7f748bcbd400, writefds=writefds@entry=0x7f748bcbd480, xfds=xfds@entry=0x7f748bcbd500) at ./src/Unix/../slirp/slirp.c:368 #10 0x000055f81489c797 in slirp_receive_func(void*) (arg=<optimized out>) at ./src/Unix/ether_unix.cpp:836 #11 0x00007f74909acfa3 in start_thread (arg=<optimized out>) at pthread_create.c:486 #12 0x00007f748f9e482f in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:95 (gdb) list ip_input.c:435,460 435 436 /* 437 * IP timer processing; 438 * if a timer expires on a reassembly 439 * queue, discard it. 440 */ 441 void 442 ip_slowtimo() 443 { 444 register struct ipq *fp; 445 446 DEBUG_CALL("ip_slowtimo"); 447 448 fp = (struct ipq *) ipq.next; 449 if (fp == 0) 450 return; 451 452 while (fp != &ipq) { 453 --fp->ipq_ttl; 454 fp = (struct ipq *) fp->next; 455 if (((struct ipq *)(fp->prev))->ipq_ttl == 0) { 456 ipstat.ips_fragtimeout++; 457 ip_freef((struct ipq *) fp->prev); 458 } 459 } 460 } [3] diff -Nurp orig/basilisk2-0.9.20120331/src/slirp/ip.h try1/basilisk2-0.9.20120331/src/slirp/ip.h -typedef caddr32_t ipqp_32; -typedef caddr32_t ipasfragp_32; +typedef void* ipqp_32; +typedef void* ipasfragp_32;
