Tool/software: TI C/C++ Compiler
Hi,
just to let you know.
If you try to compile the following code:
struct XXX {
unsigned short m1;
unsigned short m2;
union {
struct {
unsigned short data[];
} raw;
struct {
unsigned int data[];
} _u16;
struct {
unsigned long data[];
} _u32;
struct {
unsigned long long data;
} _u64;
struct {
unsigned short MX;
insigned int MY;
} _s3;
} uuu;
} xxx;
your compiler can report the following error:
INTERNAL ERROR: C:\ti\ccsv7\tools\compiler\ti-cgt-msp430_16.9.0.LTS\bin\acpia430.exe experienced a segmentation fault
while processing function (unknown or file scope) file (unknown) line 0
This is caused by a defect in the compiler itself. TI Customer
Support may be able to suggest a workaround to avoid this.
Upgrading to the newest version of the compiler may fix this problem.
Contact TI in the E2E support forums at http://e2e.ti.com under
"Development Tools", "TI C/C++ Compiler". See the link titled
"Submitting an issue". Include this ENTIRE error message and a
copy of the .pp file created when option --preproc_with_comment
(-ppc) is used.
To fix it you have to define the lengths of arrays, for example like:
struct XXX {
unsigned short m1;
unsigned short m2;
union {
struct {
unsigned short data[8];
} raw;
struct {
unsigned int data[4];
} _u16;
struct {
unsigned long data[2];
} _u32;
struct {
unsigned long long data;
} _u64;
struct {
unsigned short MX;
insigned int MY;
} _s3;
} uuu;
} xxx;
Regards,
o.p.
