[Assist] IceCat: SIGSEGV in safe mode: How to debug?

[Rudolf Dovičín]

Hello, good assistants & helpers. :-)

My IceCat 52.6.0_gnu1-4 crashes in safe mode.
GDB writes probably not very useful info:
First 40 lines like:

#0  0x00007ffff0f112f8 in  () at /usr/lib/icecat/libxul.so

(only address differ, dynamic library is the same)
and after it:

#39 0x00007ffff05b2fb5 in  () at /usr/lib/icecat/libxul.so
#40 0x00007ffff05b326f in XRE_main () at /usr/lib/icecat/libxul.so
#41 0x00005555555597f9 in  ()
#42 0x0000555555558b0e in  ()
#43 0x00007ffff7c2f223 in __libc_start_main () at /usr/lib/libc.so.6
#44 0x0000555555558d7e in _start ()

Please, how can I report it with more debugging information?
