Bowtie segfaults in pbuilder chroot at build time (Was: Issue with new version of Bowtie) (original) (raw)

[switching back to list discussion also involving debian-mentors. Please see the gdb output below I get when installing gdb inside the pbuilder chroot.]

Hi Steffen,

I intended to open an issue on Github but when doing so I wanted to leave a proof that we are using the latest upstream version:

/build/bowtie-1.2.1.1+dfsg# ./bowtie -v Segmentation fault

Hups, I think something is wrong at our side and the build has a problem.

Has anybody some spare cylces to track this down? Any volunteer?

Not really, except that on my virtual machine "bowtie -v" shows the expected (long) usage information.

I guess you try to test the existing bowtie package. Please note that I was talking about the new version in Git which I try to build and the segfault happens in the pbuilder chroot (I just learned that you are rarely using pbuilder - see subsequent fast5 uploads :-P ). So please try to build latest Git (git.debian.org seems to be offline currently). I get:

You need to setup a pbuilder hook to be able to stop the build and end up inside the pbuilder chroot.

So, I cannot immediately reproduce the behaviour you observe. What does "bowtie --version" do for you? 

See above - but we are most probably talking about different things.

Should we add "bowtie -v" as an autotest, just testing that it does not crash but that it exits with a bad code ( == 1) ?

I assume this test will not be necessary since it is not really bowtie -v which breaks but any call of bowtie segfaults inside the pbuilder environment.

Another question to me is why we do not have a bowtie-dbgsym package. Where is it?

No idea but hey, I installed gdb into the pbuilder environment and did:

root@wr-linux01:/build/bowtie-1.2.1.1+dfsg# apt-get install gdb Reading package lists... Done Building dependency tree

Same happens when testing bowtie-align-l.

Does this ring a bell somehow?

Kind regards

  Andreas.
