Trying to emerge cscope I did enter the command 'eix cscope' and sadness ensued. <start sadness> [lambda: Gentoo]$ eix cscope * dev-util/cscope Received SIGSEGV - you probably found a bug in eix. Please proceed with the following few instructions and help us find the bug: * install gdb (sys-dev/gdb) * compile eix with FEATURES="nostrip" CXXFLAGS="-g -ggdb3" * enter gdb with "gdb --args eix your_arguments_for_eix" * type "run" and wait for the segfault to happen * type "bt" to get a backtrace (this helps us a lot) * post a bugreport and be sure to include the output from gdb .. Sorry for the inconvenience and thanks in advance! Available versions: [lambda: Gentoo]$ eix cscope </not the end of sadness> Reproducible: Always Steps to Reproduce: 1.eix cscope 2. 3.

What version??

Created attachment 205779 [details, diff] Let eix output some debug info Despite I recompiled with exactly the same FLAGS, I cannot reproduce it here. Maybe it helps if you send me your /var/cache/eix (by pm), but I am not optimistic about that. Please recompile with the attached patch and send the output of the last few lines.
I followed these instructions from a PM conversation with Martin: <instructions> svn co https://svn.gentooexperimental.org/eix/trunk cd trunk ./autogen.sh export CXXFLAGS="-O2 -g -ggdb3" ./configure make src/eix cscope (or with gdb or whatever). # edit, view differences ("svn diff") or revert edits ("svn revert file") make src/eix cscope # next edit phase... make src/eix cscope ... </instructions> The built an eix that seems to work perfectly for me (perfectly being random testing for < 5 minutes) but this cscope performs far better than one currently installed. Doing a little digging I found that I am running (portage has installed) version 18.1. The code I svn checkout build version 18.2. It appears whatever has changed has fixed my problem(s). Does anyone know when 18.2 will become an available for a ~ system? Presumably when that happen this bug can be closed.

> It appears whatever has changed has fixed my problem(s). I am not so optimistic, since nothing was changed which could obviously fix a segfault; I am afraid that it is a subtle bug concerning pointers or iterators going into nirvana somewhere, and just by accident it does not occur now. Anyway, since I see no way how to find the real cause, I will release 0.18.2.
0.18.2 is in the tree.
