Hi Timo,
It seems -proposed "18.0.5-0ubuntu0~18.04.1" is migrated to -updates. So, is it
possible to fix this in next version getting finalized for -updates ?

yes, but not before the current version in -proposed has migrated to
-updates

Crash can be reproduced by simple test application which does e.g. :
main()
{
eglGetProcAddress("egl148546488546404");
}
The problem is in the search algorithm used in mesa to look for the name
passed to eglGetProcAddress. So crash can reproduce with other names as
well. Please note that this
Yes. Problem is that bionic-proposed already has 18.0.5 staged for the
18.04.1 update, so adding more would delay getting that update.
Is there a way to reproduce this bug? How common is it? I'm wondering if
it should be skipped for now and provided via backport from cosmic after
18.10 is
Sorry, I couldn't understand what do you mean by distro patch. Do you
mean it needs to be applied as patch over the current version of libegl-
mesa0 in Bionic and libegl-mesa0 generated with this patch needs to come
as upgrade in Bionic (i.e when I do apt-get upgrade) ? thanks!

18.0.x series is done, this would need to be added as a distro patch
