Hi,
As requested by the M4 program, an error report. I could not find any directions what to report nor any indication why things go wrong. This is what I have: OS: vista ultimate, dutch. GNUwin32 installed in "C:\Program Files\GnuWin32" (by default) Another identical machine installed two months ago without any problem. When I start M4 I get the following message. E:\>m4 --help This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. m4: internal error detected; please report this bug to <bug-m4@gnu.org>: Aborted I tried to install M4 in a different directory (E:\Program Files\GnuWin32\bin) just to be shure, same results. For me this is a problem and I don't know what to do next, not enough information to continue. Kind regards, Andre Steenveld sr. Sr software engineer.
