Hello! I had a same problem with 1.5.21-0 (cygwin1.dll: file version 1005.21.0.0, build date 2006-07-30 14:21, OS: WinXP Pro SP2). Before occurrence of this problem Cygwin version 1.5.19 has been established on my computer. Today at start there was a mistake with the following message: ---- ะก:\cygwin\bin\bash.exe (enter) 8 [main] bash 4404 dll_crt0_1: internal error: couldn't determine location of thread function on stack. Expect signal problems. $ ---- I have removed the old version and have tried to install current Cygwin version (1.5.21) from mirrors.kernel.org mirror. Installation has passed successfully up to a postinstall step. On a postinstall step all Cygwin applications have crash with messages as McLay.
On my computer from the moment of last successful start Cygwin following changes have been made: 1) the some patches from Microsoft have been installed. 2) Agnitum Outpost have been updated up to version 4.0. Earlier I had no problems with Cygwin at updating other applications. Best regards, Dmitry A.
