After a failed fork, any attempt to start a new DOS shell complains that there is not enough memory, and the only recourse I have is to reboot. I was able to successfully configure and make other projects, such as automake 1.6; but the libtool configure has yet to succeed. This is probably related to the recursive make bugs that I have seen mentioned in the mailing lists - it seems to happen when a single command from the bash prompt fires off a great deal of subprocesses. Also, the configure starts out fast, forking more than one process per second; but as it progresses, process forking slows. Just before the libtool configure fails, my entire computer tends to lock up from all user input for 3 to 5 seconds or so each time another subprocess is forked. Even the Windows system clock stops ticking during a fork (although the BIOS clock remains correct); in the past, I have been compiling a large project, and over the course of 24 hours real time, the Windows system clock lost more than 2 hours from the time it spent paused during forks (although a reboot resets the clock back to the correct BIOS time). The mailing list only seems to mention forking problems on Win NT or Win 2000; and I haven't seen any mention of problems with the 1.3.10 cygwin.dll. Am I doing something wrong? Is there a quick fix to the problem? Or is there something that I could do to help you debug this problem? $ cygcheck -s Cygwin Win95/NT Configuration Diagnostics Current System Time: Tue Mar 12 23:16:20 2002 Windows 98 Ver 4.10 Build
