When?  If Emacs seems to hang, it means it's stuck in an (almost-)inf-loop,
and you can try stopping it a few times and compare the backtraces.
The one you show was taken from within the GC, which always leads to such
long lists of `mark_object', so better skip that backtrace and try
another one.
In any case the backtrace you show seems not to be from a regexp-match.
You could try and check the value of Vinhibit_quit with

    (gdb) p Vinhibit_quit
    (gdb) xtype
    <should say it's a symbol>
    (gdb) xsymbol
    <could say "nil" or "t">


PS: It's also useful sometimes to show the result of xbacktrace (see
    etc/DEBUG as well for more info about debugging in general).
