Re: [Chicken-hackers] [PATCH] mutex-lock! sometimes not srfi-18 compliant

2015-11-24 Thread Jim Ursetto 
Use git commit --amend to fix if you haven't committed the second one yet.

Use git rebase -i to squash existing commits together.

[Chicken-hackers] How to interpret chicken post mortem?

2015-11-24 Thread Jörg F . Wittenberger 
Hi all,

just managed to switch to the master branch, eventually.  (Congrats to
myself, sight ;-)


Now there is a segfault.  Looks almost random.   The program runs for a
fairly long time until crash.  (Megabytes of chicken -:r backtrace and
no hint either). Some gdb backtraces from a debug build below.

Anybody having an idea how to narrow this down?

Thanks so much

/Jörg
