| 2 | |
| 3 | Hit a ICE and could reduce it to the following minimal example: |
| 4 | |
| 5 | 1. Only the size of array assigned with 2 caused the issue: |
| 6 | $ cat > mipgcc-test.c << END |
| 7 | |
| 8 | int main (int argc, char **argv) |
| 9 | { |
| 10 | char *pStrArry[ARRAY_SIZE_MAX] = {"hello"}; |
| 11 | int i = 0; |
| 12 | |
| 13 | while(pStrArry[i] && i<ARRAY_SIZE_MAX) |
| 14 | { |
| 15 | printf("%s\n", pStrArry[i]); |
| 16 | i++; |
| 17 | } |
| 18 | |
| 19 | return 0; |
| 20 | } |
| 21 | |
| 22 | END |
| 23 | |
| 24 | 2. Only -O1 and -g on mips caused the issue: |
| 25 | $ mips-poky-linux-gcc -O1 -g -o mipgcc-test mipgcc-test.c |
| 26 | mipgcc-test.c: In function 'main': |
| 27 | mipgcc-test.c:18:1: internal compiler error: in dwarf2out_var_location, at dwarf2out.c:20810 |
| 28 | } |

| 30 | Please submit a full bug report, |
| 31 | with preprocessed source if appropriate. |
| 32 | See <http://gcc.gnu.org/bugs.html> for instructions |
| 33 | |
| 34 | 3. The quick workround is trying to enlarge the size of array with larger |
| 35 | than 2. |
| 36 | |
| 37 | 4. File a bug to GNU, but it could not be reproduced on there environment. |
