(In reply to Michael Palimaka (kensington) from comment #4) > Could you please check dmesg for exactly what's segfaulting, and ideally run > that failing uic_wrapper in gdb and get a backtrace? Since I was present when this was brought up on IRC I may give a (partial) answer to this question: It is a *bundled* binary of UIC (that is called from within the uic_wrapper script) that segfaults. Contrast that to Jeffrey's description of what happens when the *system* UIC (as in that sudo command) is used.
I wonder if this is related to bug #639494 then.
A bit of experimentation shows that the segmentation fault actually occurs after running the export statements in the uic_wrapper.sh. If the four lines before `exec` are removed, the packages merges correctly, with and without LTO enabled. However, uic_wrapper seems to be generated during the configure stage, and I couldn't find a trivial way to fix it other than manually removing these lines after running configure. --- uic_wrapper.sh.orig 2017-12-25 16:27:51.028838827 -0500 +++ uic_wrapper.sh 2017-12-25 16:33:55.194968593 -0500 @@ -1,6 +1,2 @@ #!/bin/sh -LD_LIBRARY_PATH=/usr/lib64${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH} -export LD_LIBRARY_PATH -QT_PLUGIN_PATH=/tmp/portage/dev-qt/qtwidgets-5.9.3/work/qtbase-opensource-src-5.9.3/plugins${QT_PLUGIN_PATH:+:$QT_PLUGIN_PATH} -export QT_PLUGIN_PATH exec /tmp/portage/dev-qt/qtwidgets-5.9.3/work/qtbase-opensource-src-5.9.3/bin/uic "$@"
Oh, so this failures only occurs with LTO?
(In reply to Jeffrey Lin from comment #7) That doesn't make sense. /usr/lib64 is already in your library search path, and /tmp/portage/dev-qt/qtwidgets-5.9.3/work/qtbase-opensource-src-5.9.3/plugins doesn't even exist when I emerge qtwidgets... Have you tried re-emerging qtcore?
(In reply to Davide Pesavento from comment #9) > Have you tried re-emerging qtcore? Yes, I have re-emerged qtcore, built with and without LTO, and the same thing happens in either case. The problem occurs with and without LTO enabled. Running `export LD_LIBRARY_PATH=/usr/lib64${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}` in my terminal seems to cause all subsequent programs run to segfault.
(In reply to Jeffrey Lin from comment #10) > Running `export > LD_LIBRARY_PATH=/usr/lib64${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}` in my > terminal seems to cause all subsequent programs run to segfault. There's something seriously wrong with your system, sorry.
