 Subject: Re: [wsjt-devel] My problems while trying to get the audio samples
   
Hi Bill,

I tried again to get more information about the observed crash.

Today, I'm using r7364. The crash occurs now simply when opening the
window: help --> download samples.

I have tried to get more information using gdb. There is the thread list
after the crash:

Unfortunately, I cannot get really more information using "thread apply
1 bt". Here it is:

In my opinion, the problem is probably related to the redirection
mechanism used at sourceforge, rather as to the certificate chains. I
ignore if sourceforge has recommended as specific procedure which can
apply here.

I hope that this will help you a little bit.
