Re: [Quickfix-developers] Exception and crash

[Oren M. <or...@qu...>]

Yeah, the callstack is really there for situations where getting a=20
traditional callstack is difficult or impossible.  For instance when=20
running through a JVM or on Windows.   It is most useful when you have=20=

a repeatable crash  and you need a way to get more details where it is=20=

occurring.  It's been most useful in tracking down problems with the=20
JNI or .NET API's, however both of them have become quite stable and I=20=

haven't really found the need to use the callstack in quite some time. =20=

That code is really pretty poor and hacked together. Ironically, the=20
code designed to diagnose problems is probably the buggiest code in the=20=

distribution.  I'll probably remove it at some point or find a more=20
robust solution.
