What were you trying to do (and why)?

I installed PARI/GP using brew, and there is an odd bug that occurs. If you have code that includes the line "default(parisize, 1G)" (the second input doesn't matter as much, this is just setting how much memory the program has access to), then loading that code from the terminal encounters a problem. This bug does not occur on Linux, and appears to only occur when PARI/GP is built for Mac with clang 16, and not with gcc 14. I was informed that:

"With clang, last_tmp_file (a 64bit pointer) get changed set to 0x00000000FFFFFFFF which is precisely the return value of setjmp (32bit -1) which is very suspicious."

This does not happen if you first open the file and then call read("bug.gp"). Perhaps the package for Homebrew can be recompiled using gcc 14 (assuming this does actually fix the issue)?

What happened (include all command output)?

gp opens, but when you type in commands, the output is not printed. There is no system history either, you cannot reference computed values. If you give a syntax error, then it "fixes" itself, and the loading of the file is skipped.
See attachment for a sample output

What did you expect to happen?

I expected gp to operate normally.
See attachment for normal operation

Step-by-step reproduction instructions (by running brew commands)

1. Install PARI/GP:
   brew install pari
2. Make a file (anything, I called it "bug.gp") containing one line:
   default(parisize, 1G)
3. In that same folder, open PARI/GP and the file with the command
   gp bug.gp
4. Run any commands that are valid, e.g. 1+2, 5^2. To "fix" the error, make a syntax error like 15-

Not sure why you ticked this when the issue's title and description reference a single formula.
