Comment (by ttcoder):
I've checked haiku-files.org but builds only go back one week or so, 39571
is no longer there. And I'm not setup for building from source..
So I've prepared a bare-bones test case this morning, and found something
interesting: the crash only occurs if I link against my KISSlib.so (even
though it's not used at all in this test case); if I remove the -lKISSlib
parameter when building, the crash no longer occurs.
Here's an 'overview' of the zip-file I'm going to upload, tell me if it's
useful for you to troubleshoot this problem or if I should investigate
more on my own (and if yes, how -- I dunno where to take it from here
:-)..
