simple source file illustrating the problem
Hi,
I try to catch floating point exceptions (underflow in my example).
My full code need to be compiled with -lpthread option.
When i add a print (or a write) in the trap function, the print doesn't work if
compilation was done with -lpthread option (even if no thread function is used)
Removing the print restore a normal behavior.
The problem appears with all versions of gfortran I have tested : 4.4, 4.7,
5.1, 5.3, and 6.3
The executable is obtained with following command :
gfortran -ffpe-trap=denormal -lpthread prog.f90
The source file prog.f90 is attached (less than 30 lines)
