Package: libclang-cpp9
Version: 1:9.0.1-20
Severity: serious
Hi,
since the 1:9.0.1-20+b1 binNMU for amd64 reached sid yesterday, pocl
started to segfault.
This can be easily reproduced by installing clinfo + pocl-opencl-icd in
sid and running clinfo. The backtrace as observed in gdb:
Thread 1 "clinfo" received signal SIGSEGV, Segmentation fault.
