FIX: C1001 Error If More Than 127 Function Parameters (133107)
The information in this article applies to:
- Microsoft Visual C++ 2.0
- Microsoft Visual C++ 2.1
This article was previously published under Q133107 SYMPTOMS
When compiling a file with a function definition that has more than 127
parameters, the compiler generates this error message:
fatal error C1001: INTERNAL COMPILER ERROR
(compiler file 'd:\b_bld\c2.m2\P2\p2symtab.c', line 697)
CAUSE
Although the compiler message is unclear, which is a bug, the compiler
limit for the number of parameters passed by a function is 127. This limit
applies for any type of parameters and is by design.
RESOLUTION
Do not use more than 127 parameters for a function. One alternative is to
use a structure to pass any number of variables as one parameter.
STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed
at the beginning of this article. This problem was corrected in the
compiler that ships with Microsoft Visual C++, 32-bit Edition, version 4.0.
