Ouch! again in malloc & friends...  Looks like the bug you succeeded
to avoid by switching to a different GCC version is back, sigh.

Can you try older versions of cygwin1.dll and/or other GCC versions?

In the meanwhile I have tried with: GCC-3.4.4, 4.0.4, 4.1.2, 4.2.2, 4.2.3; with Cygwin-1.5.25-7, 1.5.25-5, 1.5.24-2 (Jan. 2007).

In all cases it fails in the same manner!


If none of that helps, I'm afraid we will need a Cygwin hacker on
board to help us debug this.

I suspected it...

Can you ask someone on the Cygwin list
to volunteer?

I will try.

Thanks,
   Angelo.
