We're seeing transient segfaults in gvBurnScanline with a huge in-memory
raster created by rasterio.
The raster size is (67264, 51776).
The segfaults happen in cloud servers, not in laptops or local virtual
machines.
Debugging is hard because rasterio installs its own libgdal but with gdb
I see with bt
#0 __memset_avx2_unaligned_erms () at
../sysdeps/x86_64/multiarch/memset-vec-unaligned-erms.S:245
#1 0x00007ffff127646f in gvBurnScanline(void*, int, int, int, double) ()
from ../rasterio/.libs/libgdal-c9384152.so.20.5.0
Any ideas?
Thanks,
Ari
