Comment (by danq@…):

 News: Last night, I significantly increased the size of the run-time stack
 and the problem went away.  Since you mentioned that cpp_int does not
 effect stack usage, I suspect that somewhere else in my code, the stack
 was getting loaded and by sheer chance, wound  up clobbering my cpp_int
 variable.

 I will play with GDB to see if I can pinpoint the cause.

 I will also take a look at 1.54 and try to reproduce the problem with that
 version.

 Thanks!

 Dan
