Hi!
I tried to debug the latest entry to the BUGS file, and stumble upon
problems using gdb on the .static file. :) I just tried again with the
*dynamic* tclh, and here are my results.
I had a more significant backtrace than last time, however, I don't
get it:
Program received signal SIGABRT, Aborted.

So the bug is (triggered?) in tvision. A potential suspect:
void * allocBlock( size_t sz )
{
assert( heapcheck() >=3D 0 );
sz +=3D BLK_SIZE;
in lib/new.c. What's heapcheck? I can't seem to find it anywhere.
Internal gcc?
Anyways, this is probably not a problem in tclh...
