Error description
When compiling the scenario test case below with debug information (using -g), the compiler is generating an invalid stabstring for the RCSid variable. The disassembly of the stabstring reads: .stabx "rcsid:c=s""TESTBADSTABSTRING""",0x03,0x81,0x0 As a constant object, the stabstring grammar requires a ';' at the end of the string: .stabx "rcsid:c=s""TESTBADSTABSTRING"";",0x03,0x81,0x0 Applications that use object file stabstring debug information may encounter problems when parsing the invalid stabstring. For example, the AIX linker's -bstabcmpct:2 feature outputs the following error with the -bloadmap option: ld: 0711-397 STABSTRING ERROR: Symbol table entry 24, object file foo.o Character ; expected in production Stabstring. ASCII 0 seen. Remainder of stabstring is: ===== TESTCASE ===== program test CHARACTER*(*) RCSid parameter (RCSid = 'TESTBADSTABSTRING') write (*,*) 'TEST' stop end $ xlf90 -g foo.f -bstabcmpct:2 ** test === End of Compilation 1 === 1501-510 Compilation successful for file foo.f. ld: 0711-395 STABSTRING ERROR in object foo.o ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information. ld: 0711-937 SEVERE ERROR: Severe errors have occurred. $
Local fix
- Avoid usage of the -bstabcmpct:2 feature - Manually edit the object file/disassembly to read the missing ';' character - Do not use debug information
Problem summary
PROBLEM DESCRIPTION: A truncated stabstring is making the linker -bstabcmpct:2 feature fail. USERS AFFECTED: Users with a string in a parameter statement, compiling with stabstring debug information, and using the -bstabcmpct:2 linker feature.
Problem conclusion
The stabstring generation was corrected.
Temporary fix
