Adding a google calendar in korganizer results in korgac (korganizer-related daemon) to crash every startup. Maybe related to this bug https://bugs.gentoo.org/679764 though, the same version of libkgapi used to work fine before updating akonadi and related packages to version 18.12.3-r1.

I'm having exactly the same problem after upgrading to -r1 version.
I disabled akonadi-18.12.3-major-regression-updating-attributes.patch and akonadi-18.12.3-collection-detach-at-wrong-time-in-attribute.patch, rebuilt affected packages and no more crashes.
Created attachment 574850 [details, diff] calend.patch diff -u user patch
Comment on attachment 574850 [details, diff] calend.patch Well same problem, /usr/bin/korgac, from the just emerged package kde-apps/korganizer-18.12.3-r1, crashes episodically, sometime it does, sometime it doesn't, with googlecalendar plugin active. I traced down the problem with gdb to this SEGV: Thread 1 "korgac" received signal SIGSEGV, Segmentation fault. 0x00007ffff72d30c9 in Akonadi::BlockAlarmsAttribute::isAlarmTypeBlocked(KCalCore::Alarm::Type) const () from /usr/lib64/libKF5AkonadiCalendar.so.5 which seems to point to the package kde-apps/akonadi-calendar-18.12.3-r1 source file src/etmcalendar.cpp. The same problem is referenced upstream in this thread: https://bugs.kde.org/show_bug.cgi?id=406411 apparently solved in version 19. Trying to solve the problem in the current gentoo version, I did some hacking using the updated git source file of etmcalendar.cpp https://github.com/KDE/akonadi-calendar/blob/master/src/etmcalendar.cpp, creating, with a "diff -u", the attached user patch. It seems, at least, enough to keep korgac alive, meanwhile we wait for the 19 version. I hope it may helps to track the real BUG.
Thanks for digging this out, please test the following commit: https://cgit.kde.org/akonadi-calendar.git/commit/?h=Applications/19.04&id=c9129b07b42097f6b5eb54c2103d22a9c2263d83

And I hope, thanks to this patch, I understood the semantic of this bug. It is, I guess, what happens when a programmer forget to think to the machine code a compiler generates and only watch to the estetical shape of source code. This fragment of code: int a = 1234; { int b = 5678; } int c; printf ( "%p %d\n", &c, c); where the last printf statement is going to print "5678" because "c" it has been allocated on the same stack address of "b", should point to the very same mistake we have seen corrected by this patch. The source code doesn't look nice as: int a = 1234; int b = 5678; { } int c; but the semantic is wrong and the compiler generates the wrong code. Thanks so much. I guess we may consider FIXED this BUG.
Thanks for testing.
