Why flex doesn't work in new version of cygwin (1.5.3)

[lijun xu]

Dear all,

I have a program that uses c++ class generate by flex.exe. It runs well  in the version (1.3.10). When I upgrade to the latest version (1.5.3).The program always return "Exception: STATUS_ACCESS_VIOLATION".The content of dump file is as follows:
Exception: STATUS_ACCESS_VIOLATION at eip=35B31200
eax=FFFFFFFF ebx=0022F784 ecx=00000000 edx=00000000 esi=0A046130 edi=0A046A08
ebp=3F5F4FB5 esp=00224118 program=E:\cygwin\home\Administrator\Test\mctester.exe
cs=001B ds=0023 es=0023 fs=0038 gs=0000 ss=0023
Stack trace:
Frame     Function  Args
 220306 [main] mctester 1076 handle_exceptions: Exception: STATUS_ACCESS_VIOLATION
 251474 [main] mctester 1076 handle_exceptions: Error while dumping state (probably corrupted stack)
Any help is appreciated.
