Hi,
I'm having strange crashes in GDAL (SVN) when called via GMT. The crashes
occur at a call to
GDALClose(hDataset);
Now, this is only occurs when I try to read a sub-region of a grid but
those are GMT details.
It doesn't happen to colleagues on OSX but they are using gdal 1.11. Can't
say that's the reason but this used to work for me as well on Windows (I
should know because I wrote that code).
I built a GDAL debug and can see that the crash happens in
cpl_atomic_ops.cpp
int CPLAtomicCompareAndExchange(volatile int* ptr, int oldval, int newval)
{
return (LONG)InterlockedCompareExchange((volatile LONG*)(ptr),
(LONG)newval, (LONG)oldval) == (LONG)oldval;
}
because the 'ptr' is invalid. That function is called by
gdalrasterblock.cpp
GDALRasterBlock::DropLockForRemovalFromStorage()
if( CPLAtomicCompareAndExchange(&nLockCount, 0, -1) )
and the debugger tells me that
nLockCount <Unable to read memory>
and here I'm lost. Where is nLockCount supposed to be set?
Thanks
Joaquim
