crash when entering close bracket } in math mode adjacent to $

XEmacs Users <machine, os, target, libraries (multiple lines)> System: SunOS palm.phys.psu.edu 5.8 Generic_108528-14 sun4u sparc SUNW,Ultra-5_10 Architecture: sun4 I can reproducibly generate a crash when editting text inside math mode $$ and entering a close bracket \}. A sample is provided below. I don't know the details of how xemacs was installed, but the people at help(a)phys.psu.edu would know. This is a piece of a latex file being editted. Notice how the first math mode has squiggly brackets around the vector. When squiggly brackets are added to the vector in the second piece of math mode, the final backet `\}`, added just before the closing $, crashes xemacs reproducibly. This condition can be satisfied by a properly designed genetic search. A genetic search parameterizes a structure as a vector of generalized coordinates $\{a_1, a_2, ... a_N\}$ and generates a new structure $C$ by combining the coordinates of two known structures $A$ an $B$ at a random crossover point $M$: $C = (a_1, a_2, ... a_M, b_{M+1}, b_{M+2}, ... b_N)$. These structures are eva One can work around the problem by eliminating math mode, adding the bracket, and then restoring math mode.
