I built source package nodejs_18.19.0+dfsg-6~deb12u2 in Debian
Bookworm i386 and installed result deb packages into system.
Packages with dbgsym were also installed.
Then I tried to reproduce segfault with simple way explained earlier
and now I see better more informative backtrace with mentioned source
files because of available debug symbols:
