Description Peter Robinson 2011-12-24 09:29:49 EST
js fails to build on ARM due to the following error during configure:

configure: error: Your compiler does not follow the C++ specification for temporary object destruction order.
RPM build errors:
error: Bad exit status from /var/tmp/rpm-tmp.y3Ssej (%prep)
    Bad exit status from /var/tmp/rpm-tmp.y3Ssej (%prep)
Child returncode was: 1


Looking at the configure.in test case its documented as:

dnl ========================================================
dnl Test for correct temporary object destruction order
dnl ========================================================
dnl We want to make sure the compiler follows the C++ spec here as 
dnl xpcom and the string classes depend on it (bug 235381).

Are you think it is incorrect check? I think it is gcc issue on arm. Reassigning.
Comment 2 Jakub Jelinek 2012-01-01 16:46:44 EST
Can you post the relevant config.log snippet (what compiler messages were emitted if any, if it was a compile time failure or runtime failure)?

Can you compile:
extern "C" void exit(int);
class A {
  A(int& x) : mValue(x) {}
  ~A() { mValue--; }
  operator char**() { return 0; }
  int& mValue;
void func(char **arg) {}
int m=2;
void test() {
  if (m==1) m = 0;
int main() {

and run it, see what exit status it returned with?
Comment 3 Peter Robinson 2012-01-26 09:42:51 EST
Fixed. Issue in js.
