Bug #: 55650
Summary: [4.8 Regression] Firefox profiledbuild: libxul.so:
cannot map zero-fill pages: Cannot allocate memory
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: gcov-profile
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: markus@trippelsdorf.de
Building Firefox with:
make -f client.mk profiledbuild
Results in:
...
/var/tmp/moz-build-dir/dist/bin/xpcshell: error while loading shared libraries:
libxul.so: cannot map zero-fill pages: Cannot allocate memory
make[4]: *** [prepare-package] Error 127
% readelf -lSW ./libxul.so
There are 41 section headers, starting at offset 0x103e7f10:
Section Headers:
[Nr] Name Type Address Off Size ES Flg
Lk Inf Al
...
[28] .bss NOBITS 000000000bfaabe0 bfa9be0 80186ae8c 00
WA 0 0 32
Adding Wl,-Map,libxul.map when linking libxul shows:
...
.bss..LPBX1 0x000000000ccb3be0 0x800000000
/var/tmp/moz-build-dir/toolkit/library/../components/protobuf/once.i_o
....
Reducing once.cpp leads to:
% cat test.ii
class A
{
virtual void Run ();
};
class B:public A
{
public:
B ();
void Run ()
{
}
};
void *operator new (unsigned long)
__attribute__ ((__externally_visible__));
void *moz_xmalloc ();
inline void *operator
new (unsigned long)
{
return moz_xmalloc ();
}
inline A *
NewCallback ()
{
return new B;
}
% c++ -c -fprofile-generate -fdata-sections -O2 test.ii
% readelf -lSW ./test.o | grep "800000000"
[11] .bss..LPBX1 NOBITS 0000000000000000 000120 800000000 00

A backport to 4.7-branch looks easy and appropriate.
Jakub, can you handle this?
