Compiler May Hang Under DOS When Using /qc and Memory Runs Out

Summary:

Under certain circumstances, the compiler may run out of memory when

trying to compile a source module. In some situations, when both

compiling under DOS and specifying the /qc option to invoke the quick

compiler, an out-of-memory condition may result in garbage output

being dumped to the screen, or the following error may be generated:

fatal error C1063: compiler limit : compiler stack overflow

Depending on the particular code being compiled and the optimizations

specified, the C1063 error may or may not contain any error text. In

some cases, only the error number is displayed and then the computer

hangs before the "compiler limit" message is displayed.

This problem has been observed only with the real-mode quick compile

option. Simplifying the code is one way to work around the problem.

Microsoft has confirmed this to be a problem in C versions 6.0, 6.0a,

and 6.0ax. We are researching this problem and will post new

information here as it becomes available.
