OM reports an error in the C code it creates

[massimo ceraolo]

If I run (using OM r20199) "gridTest21" of the enclosed package "AutoCreateBug" I get the following message:

"C:\Programmi\OpenModelica1.9.1Nightly\\MinGW\bin\mingw32-make.exe" -f AutoCreateBug.gridTest21.makefile
gcc   -falign-functions -msse2 -mfpmath=sse     -I"C:/Programmi/OpenModelica1.9.1Nightly//include/omc/c" -I. -DOPENMODELICA_XML_FROM_FILE_AT_RUNTIME  -c -o AutoCreateBug.gridTest21.o AutoCreateBug.gridTest21.c

mingw32-make: *** [AutoCreateBug.gridTest21.o] Error 1

It seems that OM creates for this model a C file that is invalid.
