Breaks here too, using pdftex 1.40.0, context 2006.12.27, Ubuntu i386: *** glibc detected *** pdfetex: free(): invalid next size (fast): 0x082d42f0 *** Running texexec with --verbose says what the pdftex command that texexec runs is, and this is the minimal version of it: pdfetex -fmt=cont-en b.tex where b.tex is Peter's minimal (3-line) file above. Strangely, "pdftex -etex -ini c.tex", where c.tex is b.tex with "\input cont-en" as the first line, did not crash. I rebuilt pdf(e)tex make sure not to strip the binaries, and ran it with debugging libraries and valgrind, like so: LD_LIBRARY_PATH=/usr/lib/debug: valgrind pdfetex -fmt=cont-en b.tex and the output is included below.
