traps / segfault under up-to-date debian 11 #99

Closed Rico29 closed 7 months ago

Hello fort validator often crashes with an error in kernel.log :

[208832.537689] traps: fort[663] trap stack segment ip:5592b3bf81d0 sp:7f8dcfc08640 error:0 in fort[5592b3bd6000+44000]

using fort 1.5.3 from debian 11 repositories

any idea how to debug that ? Regards

For a start, please upgrade to 1.5.4 which you can find in the Debian 11 backports archive (https://backports.debian.org/) or in Debian 12.

Did Fort print something in /var/log/syslog?

As stated in the 1.6.0 release notes, I have found and patched several instances of undefined behavior during the reviews. There is no way to prove that these caused this particular crash (particularly considering that I never managed to reproduce it, and the OP already probably left), but the code has changed so much, at this point I expect the bug to manifest in a completely different way, if at all.

Please upgrade to the latest version. If it crashes again, please open a new bug.
