The Microsoft C Compiler versions 5.10, 6.00, and C 6.00a are limited
in the number of levels deep allowed for nested for-loops. Attempts to
nest for-loops too deep will result in the error "C1026: parser stack
overflow, please simplify your program."
There is no specific limit to the nesting level because the parser
stack capacity depends on the actual contents of the code, but the
overflow generally occurs with for-loop nesting about 10 to 15 levels
deep. This is an arbitrary limit and it will be increased in the
future to ensure compatibility with the 15 nesting-level minimum
specified in the ANSI specification.
Microsoft has confirmed this to be a problem in C versions 5.10, 6.00,
and 6.00a. We are researching this problem and will post new
information here as it becomes available.
