[Github-comments] [geany/geany-plugins] Splitting a snowman in half crashes Geany with Spell Check (inserting a space before Unicode VARIATION SELECTOR-16) (#1041)

[Miro Hrončok]

> FWIW I just tried to compile Geany master with Clang as well as with [what seem to be Fedora's hardening flags](https://fedoraproject.org/wiki/Changes/Harden_All_Packages), yet I still can't reproduce.

FTR the cflags in Fedora are:

    -O2 -flto=auto -ffat-lto-objects -fexceptions -g -grecord-gcc-switches -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -fstack-protector-strong -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1  -m64 -mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection

And ldflags:

    -Wl,-z,relro -Wl,--as-needed  -Wl,-z,now -specs=/usr/lib/rpm/redhat/redhat-hardened-ld

And we don't use cgal but gcc.

> @hroncok what happens if there is no snowman in sight, but you have a space character followed by the code point FE0F (which you can enter as `<ctrl><shift>u` all at once and you get a funny `u` then `fe0f` and `<enter>`).

A crash.
