Weird define issue

[dany-on-demand]

Using latest version. Not sure about this one. Mini repro:

common.h:

#ifndef COMMON_H
#define COMMON_H
#define IF_MALLOC_ERROR(result)                                                                                    \
    if(!result) {                                                                                                         \
        LOGF("Critical error: malloc failed (%s:%d)", __func__, __LINE__);                             \
        exit(1);                                                                                                       \
    }
#endif

main.c:

#include "common.h"
void main() {
    unsigned char* data = malloc(8 + 1);
    IF_MALLOC_ERROR(data)
}

Results in this error:

Unhandled expr() node {PredefinedExpr} (cur_file: ".\main.c"):

    id: '0x1f7c59b5850'

Can be easily fixed by copying the definition, you don't even have to remove the definition from common.h & it works:

common.h:

#ifndef COMMON_H
#define COMMON_H
#define IF_MALLOC_ERROR(result)                                                                                    \
    if(!result) {                                                                                                         \
        LOGF("Critical error: malloc failed (%s:%d)", __func__, __LINE__);                             \
        exit(1);                                                                                                       \
    }
#endif

main.c:

#include "common.h"
#define IF_MALLOC_ERROR(result)                                                                                    \
    if(!result) {                                                                                                         \
        LOGF("Critical error: malloc failed (%s:%d)", __func__, __LINE__);                             \
        exit(1);                                                                                                       \
    }
void main() {
    unsigned char* data = malloc(8 + 1);
    IF_MALLOC_ERROR(data)
}
