It is Bug 1560010 which is already backported to F-28 but F-29/Rawhide still does not have the fix.
(In reply to Jan Kratochvil from comment #1) > It is Bug 1560010 which is already backported to F-28 but F-29/Rawhide still > does not have the fix. You're right, when I backported gdb-8.1.90.20180724 I should have double-checked that the fix was included. I've now just release Fedora GDB 8.1.90.20170727, which does have the fix. Tomasz, could you please give it a try with this new GDB? https://koji.fedoraproject.org/koji/taskinfo?taskID=28674201 Thanks.
>Tomasz, could you please give it a try with this new GDB? > https://koji.fedoraproject.org/koji/taskinfo?taskID=28674201 With pleasure. Just downloaded gdb and gdb-headless from the links provided in koji build log.
Seems it works without crashing. However I found another issue with gdb. I'm trying to build lftp ad I found that one of the autoconf tests crashes with core. I've extracted from config.log source code of the conftest.c and after compile it crashes as same as during configure script execution however seems it crashes as well gdb.

Just in case if it is not obvious what I'm trying to do with lftp .. I'm trying to build it with LTO and seems lftp is OK however that is quite possible that LTO options which I'm passing to the CFLAGS, CXXFLAGS and LDFLAGS may be causing that simple test program is core dumping and additionally core file generated out of executable with such option is crashing gdb as well. In other words here it may be not one but two bugs. Should I raise second ticket against gcc?

Would it be possible for you guys to test this scratch build: https://koji.fedoraproject.org/koji/taskinfo?taskID=28721550 ? I can reproduce the issue with the GDB that's installed via dnf on rawhide, but I cannot reproduce the issue with this scratch build.
After some investigation, Jan and I have tracked down the problem to Bug 1609577. I have now triggered a new GDB build on Rawhide which should fix the problem. I'm still leaving the needinfo flag just to make sure that this new build will work for Tomasz and Severin.

(In reply to Tomasz Kłoczko from comment #14) > Looks like new gdb is not crashing. Thanks for testing.
