as aborts after buffer overflow

[Peter Kozich (GM)]

Dear,

compiling the attached example fails with this error message:

*** buffer overflow detected ***: terminated
/tmp/ccyb3JRr.s: Assembler messages:
/tmp/ccyb3JRr.s: Internal error (Aborted).
Please report this bug.

The command line is this:

gcc -c -O1 -ggdb -masm=intel -Wa,-acdhlgn=gfp_library.lst -Wa,--
listing-lhs-width=4,--listing-rhs-width=132 -o gfp_library.o
gfp_library.c


There are a number of ways to get it compiled: -O0 instead of -O1,  or
omitting  ,--listing-rhs-width=132,  or omittig -ggdb,  or eliminating
the get_realloc() function and replacing its call with its return
expression in the caller.

But the problem is that such solutions don't always work: the original
gfp_library.c is more complex and the simple solution of using -O0
didn't help.
