beginning with 20060811 I began seeing crashes such as bug 341815 comment 15 on the trunk windows debug builds in browser tests in (at least) js1_7/iterable/regress-341510.js js1_7/iterable/regress-341815.js js1_7/geniter/fibonacci-matrix-generator.js > ntdll.dll!_RtlEnterCriticalSection@4() + 0x90 bytes msvcr80d.dll!_lock_file(_iobuf * pf=0x00240000) Line 238 C msvcr80d.dll!fprintf(_iobuf * str=0x00240000, const char * format=0x00553bf0, ...)

This is a pain for me trying to wade through the js test results on a daily basis... There should be a thread safe way of dumping these messages out without crashing.

I no longer see the crashes on 20060818 builds, I claim this was fixed by 348027.
