+++ This bug was initially created as a clone of Bug #55490 +++ This is the only line in a makefile: a: CFLAGS += -DMAIN There is a file a.c, which is irrelevant. I used a simple helloworld program. Run make as: binand@binand[~/testprogs]:(25) make CFLAGS+=-DMAIN a This is the output: cc -DMAIN -DMAIN a.c -o a make: expand.c:489: allocated_variable_append: Assertion `current_variable_set_list->next != 0' failed. Aborted (core dumped)
I wanted to try valgrind, but couldn't rebuild valgrind-2.2.0-5.EL4.src.rpm or valgrind-2.4.0-3.src.rpm on a RHEL3WS system.
It is fixed in RHEL4. I don't think it is severe enough to justify a RHEL3 errata at this point.
