Hello,
After sbase commits:
- 270ca025ce236885e3177cd7acfd2cfbdf6e36a5
expr: don't evaluate matched substr as a number
- e50d533d598dbe284e225e2ee52ed5f76a6e6f6a
expr: treat expressions as strs until evaluation
I fail to build linux using sbase
due to expr segmentation fault:
Linux Makefile line 1301 and 1304:
if [ $(SUBLEVEL) -gt 255 ]; then \
echo \#define LINUX_VERSION_CODE $(shell \
expr $(VERSION) \* 65536 + $(PATCHLEVEL) \* 256 + 255); \
else \
echo \#define LINUX_VERSION_CODE $(shell \
expr $(VERSION) \* 65536 + $(PATCHLEVEL) \* 256 + $(SUBLEVEL)); \
fi; \
Then i change those lines without expr:
if [ $(SUBLEVEL) -gt 255 ]; then \
echo \#define LINUX_VERSION_CODE \
$$(($(VERSION) * 65536 + $(PATCHLEVEL) * 256 + 255)); \
else \
echo \#define LINUX_VERSION_CODE \
$$(($(VERSION) * 65536 + $(PATCHLEVEL) * 256 + $(SUBLEVEL))); \
fi;
With that changes, linux successfully built.
expr segfault when doing this kind of operation:
expr $(VERSION) \* 65536 + $(PATCHLEVEL) \* 256 + $(SUBLEVEL))
Current expr can't do more than 1 operation.
Little test:
- With current sbase:
expr 2 \* 3 + 1
Segmentation fault
- With sbase before those commits:
expr 2 \* 3 + 1
7
- With current sbase:
expr 2 \* 3
6
- With sbase before those commits:
expr 2 \* 3
6
