thanks
Greetings! Here is the other issue, a segfault on input function
pointer definitions.
Any thoughts most appreciated!
Take care,

Package: cxref
Version: 1.6c-3
Severity: normal
Greetings,
When cxref encounters a function definition that contains a pointer to function
in the arguments, it segfaults. I have included a smal test file that
demonstrates what I'm seeing. The command line I'm using to reproduce this is:
cxref -xref -CPP "-E -CC -dD -dI" cxref-bomb.c
Trying to use cxref-cpp prevents the segfault, but output is empty except for
the default header from cxref. Switching the comment from the int (*f)(int,int)
to the int f is enough to get cxref through without segfaulting.
I've spent some time trying to get a handle on the fault, but I seems to lead
to the lexer or more likely the parser. If I get some time I'll try to dig
deeper on this. Maybe later this month.
Thanks for your time and efforts
-John
