gcc14/mpich-gcc14 on intel mac problem

[randolphbank]

latest Xcode 26.0.1 + command line tools: both gcc14 and mpich-gcc14 rebuit using port migrate; they installed with no problem. they compile fortran/c code with no problem but execute/immediately_hang or execute/immediately_crash depending on selected scenario. I am not a expert on theses topics but this looked suspicious to me...

BTW, I reinstalled gcc14 with -s flag but no change.

this issue has been resolved. It has to does with possible changes in firefox and chrome web browsers, possibly others as well. it is not the fault of gcc14 or mpich-gcc14, but its likely that necessary changes must be made to our codes that communicates with web browsers. thank you for looking at this.
