Error description
The compiler produces a syntax message for the following test case: ======Compile Line: xlC_r -c test.cpp ===== TESTCASE: $cat test.cpp #include <stdarg.h> typedef unsigned long vportULong; typedef long vportLong; typedef void (*vportSIG_PF)(int); extern const int vportBUILD_NUMBER; extern "C" { } extern "C" { } extern "C" { extern "C" { } extern "C" { typedef char *va_list; } extern "C" { } } typedef struct vArgListTag { va_list v; } vArgList; void galaxySignal(char *fmt, ...) { vArgList list; va_start(list.v, fmt); } int main(int argc, char **argv) { return 0; } ===== ACTUAL OUTPUT: $ /.../torolab.ibm.com/fs/projects/vabld/run/vacpp/101_com/aix/dai ly/latest/bin/xlC_r -c test.cpp "test.cpp", line 38.16: 1540-0064 (S) Syntax error: "," was expected but "." was found. $ ===== EXPECTED OUTPUT: Should compile clean
Local fix
Replacing va_start(list.v, fmt); with va_list &listv = list.v; va_start(listv, fmt); will help you workaround this issue.
Problem summary
USERS AFFECTED: Users using va_start with expressions such as a member access are affected by this issue. PROBLEM DESCRIPTION: Parser grammar for __builtin_va_start restricted to parenthesized names.
Problem conclusion
Modified the grammar to allow more general expressions and added additional type analysis for arguments.
Temporary fix
