Hrm, The crashes are less verbose with "export
DEB_BUILD_MAINT_OPTIONS=hardening=-all", "export
DEB_BUILD_MAINT_OPTIONS=hardening=-stackprotectorstrong" or "export
DEB_BUILD_MAINT_OPTIONS=hardening=-stackprotector,-relro,-pie", but
still there:
~ → xfrisk localhost
CLIENT: Connected to server.
CLIENT: Waiting for server to send client ID...Done.
[1] 11208 segmentation fault (core dumped) xfrisk localhost
The backtrace now looks as follows:
(gdb) bt
#0 CBK_IncomingMessage (iMessType=<optimized out>, pvMess=0x555500000000) at
callbacks.c:327
#1 0x000055555555cfc6 in CBK_XIncomingMessage (pClientData=<optimized out>,
iSource=<optimized out>,
id=<optimized out>) at callbacks.c:97

#3 0x00007ffff72f0dcd in XtAppMainLoop () from
/usr/lib/x86_64-linux-gnu/libXt.so.6
#4 0x000055555555a28d in main (argc=2, argv=0x7fffffffdf38) at clientMain.c:103
Nevertheless it must be something which is part of the 1.2-4 packaging
as just recompiling xfrisk 1.2-3 under the same current environment
results in a working binary.
Will continue to dig deeper. Hints welcome, though.
Regards, Axel
