L.S
This is to report a BUG in EGCS 1.1.2-pre1 (i think),
when using "-O2" when compiling the Hugs interpreter.
I'm afraid it's not too helpful as a bugreport, but I thought i report it
anyway, in the hope it triggers something...
PROGRAM: Haskell interpreter Hugs
URL: http://www.cse.ogi.edu/~mpj/hugs/hugs98.html
(older hugs 1.4 versions had the same problem)
PROBLEM: on HPUX 10.20 using egcs 1.1.1 or 1.1.2-pre1:
a SIGSEGV when the source file static.c is translated with "-O2"
WORKAROUND: 1) don't use "-O2" for the file static.c
2) use regular cc or gcc 2.7.2.3
Also NO problems on linux/386.
Please find a GDB SESSION below:
