Bug#953832: cannot allocate memory in static TLS block

Show all headers | View raw

Hi Faidon,

could you imagine to build jemalloc with --disable-initial-exec-tls
as Sergio suggests below to fix the issue in drmaa (and possibly other
packages)?

Should I open a separate bug report against jemalloc to request this?

Kind regards

      Andreas.
