2019-03-31 Thread Aurelien Jarno
This bug is very likely a bug present in old glibc versions. It has been brought to light when enabling TLS support in openblas and not by a new glibc version. Right now the bug has been workarounded by disabling TLS support in openblas. The way to handle this bug is to write a small testcase that

Great. It works. To make it clear, this is what I did to test: 1. Install libopenblas-base:amd64 (0.3.2+ds-1) and libopenblas-dev:amd64 (0.3.2+ds-1) from official repo. After installation complete, open a terminal and type gimp + ENTER. The cmd hangs forever and Ctrl-C gets a segment fault. 2.

severity 903514 important thanks > Reassigning to glibc with affects on openblas and gimp as this is caused > by a deadlock inside glibc. Done. Lowering severity as this does not render any package unusable by themselves, but only a combination of them (GIMP + OpenBLAS). I think a workaround so
