The environment, where the case came up: my Laptop: 64 Bit Intel-HW, 32
Bit Ubuntu, chicken from svn (up to date yesterday) build with
DEBUGBUILD=1.
Results: Segfault and "heap full".
Here: Debian stable, 64 Bit. Results: Success and "heap full".
Virtualbox (32 bit) with chicken-livecd-0.3.iso (downloaded is from 30th
Apr).
Results: Sucess, "heap full", Segfault
Attached a further simplified test case. It becomes clear to me that
"thread-terminate!" appears to be the problematic call. On the livecd,
we just saw about 50% Segfault and 50% success for that version of
"ttm". BUT: as soon as I coment out the call to "thread-terminate!" it
runs without problems, even in a loop.
best regards
