Hi,
recently, after some change in the source, the octave=20
development branch started to SIGSEV on exit.=20
The strange issue is that this happen only
for cygwin and not on the other platforms.
I have not yet found a solution, only a possible workaround
removing some specific C++ "free" actions, so to fallback to
libstdc++ cleaning activity.

My question however is about the gdb backtrace, is the=20
"Cannot access memory at address 0x1a" at # 9 normal ?
Unfortunately I am not really an expert on gdb:

Here the gdb session
----------------------------------------------
