6425,"Regression test: prg_exec_fail2 process runs away, mgw64 gcc 4.4, 4.5",Jim Bell <jim@…>,Gennadiy Rozental,"prg_exec_fail2.exe runs away, hogging the CPU. This is part of boost's regression test.

It happens only under MinGW-64, gcc-4.4. (gcc 4.5, 4.6, 4.7 all work).  This is likely a problem with the MinGW-64 library, but reported here as it affects boost.test.

Connecting to the runaway-process with gdb, here's what I see.

Trunk regression test...
