BUG: #pragma data_seg May Cause L1101 Error |
Q128553
1.50 1.51 1.52 WINDOWS kbtool kbbuglist --------------------------------------------------------------------- The information in this article applies to: - The Microsoft Linker (LINK.EXE), included with: Microsoft Visual C++ for Windows, versions 1.5, 1.51, 1.52 --------------------------------------------------------------------- SYMPTOMS ======== When you use #pragma data_seg() to name a data segment and the module includes a character pointer initialized to point to a string constant, the linker reports this fatal error: test.obj(test.c) : fatal error L1101 : Invalid Object Module Object file offset: xxx Record type: a0 NOTE: The error does not occur if the character pointer is not initialized. RESOLUTION ========== Here are two possible workarounds: - Use an array to set the initial value for the string. Then assign the address of the array to the pointer variable. This is demonstrated in the sample code below. -or- - Use the /ND"data_seg_name" compiler switch to name the data segment instead of using #pragma data_seg() in the code. STATUS ====== Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available. MORE INFORMATION ================ Sample Code to Reproduce Problem -------------------------------- /* Compile options needed: none */ #pragma data_seg("TEST_DATA") /* comment out this line to avoid the error */ char *pszMsg="L1101"; /* uncomment the following section and use it as a work-around */ /* char achMsg[] = "L1101"; char __far *pszMsg = achMsg; */ void main() { } Additional reference words: 1.50 1.51 1.52 5.6 5.60 5.60.220 5.60.339 KBCategory: kbtool kbbuglist KBSubcategory: LinkIss
