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

out>, page=0xfff4be8000) at om_Alloc.c:83

Hello, finally I found some time to have a closer look.
At the time of writing, I cannot reproduce the issue on the porterbox `eberlin'
with `singular` version 1:4.4.1+ds-2.
Therefore I am closing the bug.
Cheers,
Jerome
