[Gambas-user] Process.Wait freeze

[Jussi Lahtinen]

Did you run the GambasTester? It didn't get better on my box, now it
crashes randomly in two possible ways:

mTest.Process_Read.1975: #53: Stream is closed
mTest.Process_Read.1975 mTest.DoTests.1771 mTest.Main.2212

Or:

mTest.Process_Read.1975: #42: System error #9: Bad file descriptor
mTest.Process_Read.1975 mTest.DoTests.1771 mTest.Main.2212
*** Error in `GambasTestercmd': free(): invalid pointer: 0x000000000068edff
***
