2 test failures for m4-1.4.10 on NetBSD

[Thomas Klausner]

Hi!

I just tried the self tests of m4-1.4.10 on NetBSD-4.99.23/amd64.
Two failed:
test-frexpl.c:167: assertion failed
[1]   Abort trap (core dumped) EXEEXT="" EXEEXT...
FAIL: test-frexpl
...
test-printf-frexpl.c:103: assertion failed
[1]   Abort trap (core dumped) EXEEXT="" EXEEXT...
FAIL: test-printf-frexpl


Debugging test-printf-frexpl.c gives:

I'm confused. Can someone else make heads or tails of it?
