Bug description:
The sqrtl function under Clang causes an access violation when the
argument is negative.
This error occurs only under Cygwin.
This error occurs only with the sqrtl function, not with sqrt or sqrtf
Attached:
sqrt.cpp: program to reproduce the error. Compile clang sqrt.cpp and run
./a.exe
stackdump
cygcheck.out
