Please, give version net-irc/kvirc-4.2_pre5816 back to portage. Others are crashed with segmentation fault on amd64. Reproducible: Always Actual Results: $ kvirc4 Segmentation fault
4.2_pre5816 still is in the tree.
Did I say 4.2_pre5816? I mean net-irc/kvirc-4.2_pre5206. Sorry, for bad copypaste. After net-irc/kvirc-4.2_pre5206 all versions give me a segmentation fault after compilation.
Please try net-irc/kvirc-9999 and report your problem (with revision number, versions of dependencies, backtrace etc.) to upstream: https://svn.kvirc.de/kvirc
I talked with upstream devs https://svn.kvirc.de/kvirc/ticket/1146 and it looks like that this problem doesn't occur with disabled memory profiling: USE="-profile"
