Package: singular Version: 1:4.1.0-p3+ds-2+b2 Severity: important Control: affects -1 sagemath
Dear Maintainer, Singular on mips64el crashes 50% of the time when ASLR is enabled (the default). If one disables it (by using `setarch $(arch) -R`) then the segfaults go away. This affects sagemath, but I will add the workaround to it for now. In order to get a backtrace it is necessary to run `gdb -ex "set disable-randomization off" Singular` as well as install libsingular4-dbgsym singular-modules-dbgsym singular-ui-dbgsym. Then the backtrace looks like this: (gdb) bt #0 0x000000fff5901e84 in omTakeOutBinPage (bin=<optimized out>, bin=<optimized out>, page=0xfff4be8000) at om_Alloc.c:83 #1 omFreeToPageFault (page=0xfff4be8000, addr=<optimized out>) at om_Alloc.c:182 #2 0x000000fff5d6d340 in iiConvName (libname=libname@entry=0xfff4be9420 "standard.lib") at iplib.cc:1352 #3 0x000000fff5d6ea5c in iiLibCmd (newlib=0xfff4be9420 "standard.lib", autoexport=autoexport@entry=1, tellerror=tellerror@entry=1, force=force@entry=1) at iplib.cc:852 #4 0x000000fff5d9fd10 in siInit (name=<optimized out>) at misc_ip.cc:1372 #5 0x000000aaaf7b7910 in main (argc=<optimized out>, argv=0xffffb4e1d8) at tesths.cc:77 X -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (990, 'testing'), (300, 'unstable'), (200, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.14.0-3-amd64 (SMP w/4 CPU cores) Locale: LANG=en_GB.utf8, LC_CTYPE=en_GB.utf8 (charmap=UTF-8), LANGUAGE=en_GB:en (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages singular depends on: ii singular-data 1:4.1.0-p3+ds-2 ii singular-modules 1:4.1.0-p3+ds-2+b2 ii singular-ui 1:4.1.0-p3+ds-2+b2 singular recommends no packages. singular suggests no packages. -- no debconf information -- debian-science-maintainers mailing list debian-science-maintainers@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/debian-science-maintainers
