Bug ID: 2838
Summary: exim binary crashes during testsuite with Bus Error on
SPARC due to alignment issues
Product: Exim
Version: 4.95
Hardware: Sun
OS: Linux
Status: NEW
Severity: bug
Priority: medium
Component: General execution
Assignee: unallocated@???
Reporter: glaubitz@???
CC: exim-dev@???
Since version 4.95, exim crashes on SPARC on Linux with a Bus Error which
normally means that there is an alignment problem in the code.
The testsuite output looks like this on Debian unstable running on 64-bit
SPARC:
Debian-exim user found, running minimal testsuite
========================================
running minimal functionality test for binary
b-exim4-daemon-heavy/build-Linux-sparc64/exim in directory
/<<PKGBUILDDIR>>/test
Bus error
testsuite error
The full build log can be obtained from [1]. I have also observed exim crashing
on Debian unstable on Alpha and I suspect that these issues are related. Exim
4.94 is not affected by this issue.
I have already checked out exim from source and wanted to bisect the issue
myself. But have not been able to build exim from git, so I haven't managed to
find the problematic commit yet.
If anyone could give me a quick hint on how to build exim from git and run the
testsuite, I would start debugging the issue myself.
If anyone from the exim developers wants to give it a try themselves, the GCC
Compile Farm has several SPARC machines available for which an account can be
obtained by any open source developer [2].
The corresponding Debian bug report for this issue is #995679 [3].
