--- Comment #7 from john.frankish at outlook.com ---
I double-checked and found that with "bt full" I got this:

(gdb) bt full
#0  0x00007fffeae1fbb4 in raise () from /lib/libc.so.6
No symbol table info available.

I usually compile with "-g" removed and -flto, but if I leave "-g" in place and compile webkitgtk with "-DCMAKE_BUILD_TYPE=RelWithDebInfo", it fails with this the error below (see also CMakeError.log attached)

If I remove "-g" then webkitgtk compiles with "-DCMAKE_BUILD_TYPE=RelWithDebInfo" without problems, but I guess I need "-g" to get the symbol table info.
