Re: [protobuf] C++ malloc error when adding a repeated message element
Sorry for taking so long to reply, somehow this slipped through my inbox.
It does sound like this must have something to do with the runtime
environment on your embedded board. It might be interesting to try calling
malloc directly and see if you can reproduce the same kind of failure that
way, perhaps by making the same sequence of malloc calls that the protobuf
implementation would be doing internally.

Below is the .proto message definition:
message Discovery
{
uint32 lmuSerialNumber = 1;
uint64 gpsTime = 2;
repeated EquipmentInfo discoveredUnits = 3;
}
Here is the code where I'm trying to add discoveredUnits to the message:
for (int i = 0; i < numOfAssocMotes; i++)
{
EquipmentInfo* assocUnitInfo = outAssocUnitDiscoveryMsg.add_a
ssociatedunits();
assocUnitInfo->set_unitserialnumber(mySerialNum);
assocUnitInfo->set_latitude(myLatitude);
assocUnitInfo->set_longitude(myLongitude);
}
I get the malloc error when the add_associatedunits() function is
called.
Thanks,
Doug

Re: [protobuf] C++ malloc error when adding a repeated message element
Some additional information that I've obtained from the debugging process.
This malloc error is occurring in:
void RepeatedField::Reserve(int new_size)
this is in repeated_field.h.

Re: [protobuf] C++ malloc error when adding a repeated message element
Here's the error message I get during execution:
lStat: malloc.c:3695: _int_malloc: Assertion `(unsigned long) (size) >=
(unsigned long) (nb)' failed.
This code is executing on a Beaglebone ARM board running Linux RTOS. We're
cross compiling.
We have tried this same code building it on Windows and we do not get the
malloc error on Windows so we believe it is something to do with the memory
setup on the embedded board.

Doug

Re: [protobuf] C++ malloc error when adding a repeated message element
Could you provide some more details on what the error message looks like? I
don't see anything obviously wrong with your code, so it's hard to say what
the problem could be.
