Question:
is a mistake in pclose to assume that fh could be invalid
I'm not sure what you're asking here. It's not a mistake to assume that
pclose is being passed a valid fp. Linux also crashes if the fp is
closed twice.
Just as I noticed earlier on syscall.cc a defensive approuch
-----------------------------------------------
close_all_files (bool norelease)
{
cygheap->fdtab.lock ();
semaphore::terminate ();
fhandler_base *fh;
HANDLE h = NULL;
for (int i = 0; i < (int) cygheap->fdtab.size; i++)
if ((fh = cygheap->fdtab[i]) != NULL)
{
------------------------------------------------
or something is just trashing cygheap->fdtab ?
Who knows? strace should show if the fp is closed twice.
cgf
correct, it looks I have two close in excess for fd 5 and 6
Thanks
Marco
