potential crash in poppler when using "high" thread count
The issue was reported by a user of txs. We have been trying to narrow down the issue. The crash is an assert failure, apparently in FoFIType1::parse texstudio_poppler_crash_bug: strtod_l.c:1497: ____strtod_l_internal: Zusicherung »numsize == 1 && n < d« nicht erfüllt. (in English assert failed)
