Control: reassign -1 libclang-cpp13 1:13.0.0-9
Control: retitle -1 libclang-cpp13: segmentation fault (and corrupted stack)
while compiling some OpenCL kernel with pocl on i386
I managed to get a bit of a trace using ltrace -x '*' to also
catch the dlopen()ed symbols. I'm pasting just the very last
screen of output (from probably several gigabytes).
So we are segfaulting definitively somewhere inside libclang-cpp.so
# POCL_DEVICES=basic POCL_BUILDING=1 OCL_ICD_VENDORS="$(pwd)/ocl-vendors"
