I think I found the source of the problem. LyX reads the log file generated by running latex to build a list of files used as dependency. The files are extracted from the log by using a bunch of regular expressions. These regexps sometime fail to correctly extract a file name if it is truncated between lines. For example, the following is an excerpt from the log file /tmp/lyx_tmpdir1456cHRIK5/lyx_tmpbuf0/beamer-crash.log generated by MikTeX and leading to the last files above, just before the crash: ... (C:\texmf\tex\latex\beamer\beamerbaseoptions.sty Package: beamerbaseoptions 2004/11/15 (rcs-revision 1.7) (C:\texmf\tex\latex\graphics\keyval.sty Package: keyval 1999/03/16 v1.13 key=value parser (DPC) [EMAIL PROTECTED]@=\toks14 )) (C:\texmf\tex\latex\pgf\basiclayer\pgfcore.sty (C:\texmf\tex\latex\graphics\ graphicx.sty Package: graphicx 1999/02/16 v1.0f Enhanced LaTeX Graphics (DPC,SPQR) ... Notice that the line ending in "(C:\texmf\tex\latex\graphics\" really ends with a linebreak, such that graphicx.sty is not wrapped but it is on the next line (I checked it editing with vim the file). So, instead of "C:\texmf\tex\latex\graphics\graphicx.sty" the regexps extract simply "C:\texmf\tex\latex\graphics\", upon which the crc computation is tried, leading to a crash in cygwin. I'll try to come up with a patch to the LaTeX::deplog() function in src/LaTeX.C. -- Enrico
