[Texmacs-dev] A file that crashes

[bump]

The following file crashes TeXmacs 1.0.1, at least on this
machine. Deleting any part of this file (the displayed
formula, either paragraph, or the initialization material
at the end) results in a file that does not crash.

On loading the file, it is correctly displayed, but moving
the cursor around in the file quickly produces a
segmentation fault. For example if you place the cursor
at the end of the file and move up four lines, the crash
occurs when you reach the the end of the first paragraph.

  It may be checked directly that these three matrices satisfy the
  commutation relations (<reference|sltwoarcr>).

  The bilinear form
  <with|mode|math|B(x,y)=<frac|1|2> tr(x y)> on <with|mode|math|\<frak-g\>>
  is symmetric and invariant, as one easily checks.
